what should my ppm be in coco
If you’ve ever flushed a crop at the end with straight water, you would know why. I am currently in my 4th week of flower and I think I may be seeing signs of potassium deficiency. so i have tried to google my questions but not many clear answers. Depending on your plant’s maturation and the number of nutrients it can absorb, the ppm should range from 750 ppm to 1500 ppm. If EC or PPM ranges are not provided, you should use the general ranges recommended above. I hope this issue works itself out. My girls sprung back to life. My tap water comes out at about 140 PPM and when I'm done adding nutes as per the GWE schedule it's usually around 400 PPM. When considering the target EC for your nutrient solution (inflow), you need to understand that the EC will rise between fertigation events. Budsmoker187 Registered User. This is the PH buffer. While we try to make cannabis growing as simple as possible, some technical terminology is just unavoidable. Lately, we’ve had many novice growers ask us to explain PPM, TDS and EC readers, and how they all work together to help you grow better cannabis. save. Thanks for that. Clearly, cannabis plants enjoy increased parts per million as they grow. Convert all values to microsiemens of EC (values in the hundreds and thousands). It's hard to tell with the yellow HPS light but your leaves looked striped. The best ph for flowering is between 6.0 to 6.2. 400 microsiemens = 0.4 millisiemens. Was told to not even start Nutes until week 6, wanted to know what I want my feeding schedule and PPM. The PPM hardness of your base water determines the PH of the medium runoff. If you are looking for advice and support throughout your grow, we encourage you to start a Grow Journal in our Grower's Forum. Started grow in Coco only and using RO water and organic nutrients. Im using coco mixed with perlite for my grow atm, they are in week 3 of flower, however i noticed that my runoff ppm is way lower than it should be. I figure the soil is much more flexible but would still have an … However, you can only measure the EC of the inflow and the run-off. I’ve really fucked up my pH! And do you ever use plain water? I have just purchased a PPM meter and wanted to know what PPM I should be using? What should my runoff ppm be in soil? What ppm and ec values are people running thru Coco thru seedlings, veg n bloom. hide. To get an EC value, multiply the ppm reading by 2 and divide by 1000. Your main management goal is keeping the run-off value close to your run-off target. Do you have a closer pic of the leaves. The founder of I Love Growing Marijuana, Robert Bergman, is a marijuana growing expert … But you have another dimension to coco in that normal interval feedings of F/W/F/W can be changed to something like F/F/F/W. Not sure how much cal mag I should add to the fertigating water. Always so they been veg for a few weeks since and seem all ok now. The run-off EC is the best proxy for the EC of the nutrient solution in the coco. If you rinse your coco coir more than three times and it’s still showing 450 or more ppm, and/or the pH is out of range, do not use that coco coir. The Science and Practice of Growing Cannabis. Check with the breeder or do research on your strain. Never let a plant go more than a few days without testing her run-off EC. If EC or PPM ranges are not provided, you should use the general ranges recommended above. keep flushing until your run off ppms are very close to input ppms. Using distilled water or water filtered through reverse osmosis is best. PPM stands for “parts per million” and is a unit of concentration. Regardless you should only add nutrients if your ppm level's get low, and only then if you are experienced and you ladies show signs of deficiencies that only fertilizer can solve. Listen to your plants! We ran a test with the Pioneer Coco from Batch 64 to see if we could lower the ph and ppm (ECx500) of the water coming out of the coco. Your plants know better than anyone what EC they prefer. 2. The only reason that I suggest 1/4 strength nutes is because I know there is no risk to the plants. The max ph range you’d want would be 5.5 to 6.5, growing pot in coco outside of that pH range will cause nutrient problems. So if I want a ppm of 720, I set it at 840, ... Lucas stresses that you should always use FULL STRENGTH nutes. My solution going in is around 750ppm, but im using cyco so apparently that's equivalent to 1100 or so ppm. If you are starting with low EC water, the bulk of the EC will come from the base nutrients. This buildup persists for a while, and then slowly dissolves back into the runoff, resulting in a higher PPM. Grow Your Own, But Don't Grow Alone... Let's Grow Together! Realize: Plants may be burned by abrupt changes, but they may be able to adjust to the new higher levels. If you have plant nutrient recommendations in EC units, an EC meter is convenient. PPM (Parts per Million) levels is the measure of nutrients in the water used to feed your cannabis plants. Since I started checking my run off and upping my nutes I noticed my run off ppm has been lower but my ph is still higher. Make any changes slowly and always verify that your plants approve of the change. Coco nutes should be here Friday. Help! Ph is within range. Is it better to use an EC or a TDS meter? For example, if the EC of the starting water is 150, then your EC target for the nutrient solution (inflow) can be adjusted by +150 points. If so, that could be a problem. For example: let’s say there are 3 lbs of cannabis compared to 1,000,000 lbs of water, we would say the concentration of cannabis is 3 ppm. Could someone PLEASE help me understand. How often do you feed? If however the runoff starts off low or at 1,200 ppm you can take your nutrient load up a bit. Therefore, in addition to lowering inflow EC, you should also increase fertigation frequency. Yess finally buds are on there way. There are minerals in the tap water you will use to water your plants and you will be adding some fertilizer solutions to the water which also can be measured in parts per million. The "EC-to-TDS Conversion Factor: NaCl (avg. I used to but apparently im supposed to use nutes constantly in coco, i do a flush once a week though with a salt clearing agent. One thing I do is keep a separate bucket of water at 6.0ph, when my reservoir levels drop I just top it off with this water. Running autoflowers, medium Happy Frog soil, fox farm nutrient trio and call mag. My tap water is PH 7.5 reading 199PPM. If the runoff is higher than 1,200, like 1,500 ppm, then the plant is not uptaking what you are putting in and is just wasted. And if your ppm is 500: 500*2/1000= 1 EC . It is set for the standard EC targets, with no grow specific adjustments. Lightly wet the coco medium (too damp won’t encourage root growth). Coco specific nutrients do this very well.. they also need to be stronger, there should be no difference in Drain to Waste and Recirculating feed charts, coco consumes the nutrients the same way regardless of the setup. By the end of 6 gal runoff is near ppm of what i put in (300ppm). I also did a flush today with the same results. But … Check out our Product and Equipment Guide for our Recommended Grow Lights, Grow Set-up Equipment, DIY Projects, Germination Supplies, Plant Training Supplies and everything else you will need during the grow! I am soooo confused and have never had this problem before.. i am in my last stages of veg and I decided to check my runoff it was anywhere between 2000 too 3000 Ppm and ph was coming out at 6. What's your ratio of liquid cal-mag to mega crop? Therefore, you should start with the recommendations from your supplier. Add and subtract EC for each of the 5 variables below based on the particulars of your grow. I water with nutes every other day. 750ppm in yet 4000 ish coming out. I'm going to add more bloom nutes next run. im within a WEEK of starting my first hydro grow (WOO HOO!! ) The key consideration is the EC. I read somewhere else the ppms are low because the nutes are being used up? Lowering the EC makes it easier for plants to pull in all the water that they need. Therefore, the target for the EC of the inflow is always lower than the maximum acceptable run-off score. So I flush with 300ppm 6 gal of solution per plant, checking ppm run off at 2 gal, 4 gal, and 6 gal. When calculating your target inflow EC, you need to start with the low end of the recommended range. *EC units are expressed in microsiemens. My runoff ppm is almost double what I'm putting so should I give a plain/calmag watering? The lower the initial EC the better. Can you take a closer pic of the leaves? If you are growing a strain that likes “high nutes” then you may increase the inflow target, and work with a higher range. 100% Upvoted. Around 400. Coco coir should be watered when it’s 50–70 percent dry. If you are using reverse osmosis water, the reading will be 0 to 10 ppm as it is completely free of minerals. Do not adjust the target more than +300 points. I grow in coco so I can see how they react within a day or 2 normally. You should start by checking run-off daily until the numbers become predictable to you, at which point, you can skip days. I know there’s a lot of debate regarding CalMag in coco, and if it should be added with every feeding or even at all. My head hurts from reading so much about pH, PPM and EC. However, natural PPM is 350 out of the tap. However- the ppm it displays could be 500, 640, or 700- depending on the tester used. No just water, its suppose to clear salt build up and they suggest using it once a week. 2 comments. Ph is also coming out around 6.9-7.0. RO water works perfectly in bringing this down as low as needed with simple additions, so my question is, what is the ideal PPM for a coco and soil grow both? So from now on I feed my base nutrients at full strength (4mL per liter) and use my other nutes at 1/4 to 1/2 depending on how they look. When calculating your target inflow EC, you need to start with the low end of the recommended range. Once you determine your target inflow EC and are maintaining the EC in your coco within 300 points, make sure that your plants are happy! On top of that, the physical appearance of coco coir isn’t necessarily a reliable gauge for knowing when the medium needs more water. If you are unable to fertigate frequently, then it will be harder to maintain a tight range between inflow and run-off EC values. What should your coco run off be? You should also be using a ppm meter to measure total dissolved solids while you’re measuring the pH. ... but now I have changed to coco tec as it's easier to order and works good just been adding the … Slowly run 2x to 3x your container size of plain pH’d water to really flush it out. High frequency fertigation is the best practice. For example: let’s say there are 3 lbs of cannabis “diluted” in 999,997 lbs of water (for a total of 1 million even), we would say the concentration of cannabis is 3 PPM for those given weights. If the starting water already has a high EC, you should adjust your target to account for the EC of the starting water. I'm experimenting with both. As I discuss in more detail below, you are always working to maintain EC within about a 300-point range. Coco specific nutrients do this very well.. they also need to be stronger, there should be no difference in Drain to Waste and Recirculating feed charts, coco consumes the nutrients the same way regardless of the setup. With soil cultivation, the water ppm should be checked after adding additives to the watering vessel. See our tutorial “How to Manage Cannabis Fertigation by Measuring Run-off EC/PPM”. I suggest you flush with 1/4 strength nutes instead of that clearing agent. You definitely want a pH between 5.8 – 6.3 (Lower for hydro, higher for soil). Managing the Electrical Conductivity (EC) of the water that is available to the plants is a key practice to maximize the speed of growth and yield of the harvest. 0.5) " from my meter shows that it is part of the "Hanna" group in the PPM conversion chart or what many just call a "500 scale" meter. Beyond the supplier’s recommendations there are several variables that you should consider to fine tune your EC target. In the chart below, you can find general guidelines for optimal EC at different life stages, however, there are differences between different nutrient lines. Discussion in 'First Time Marijuana Growers' started by ElChoppo, Jul 20, 2018. We used a 1 gallon pot of coco for each test. If your withing 200ppm + or - and your ph is between 5 to 6.3ish you should be golden. I've been doing a cal mag foliar spray twice a day and I'm already at 500 ppm of only mega crop in the fertigating water. We explain the importance of EC in “Growing Cannabis in Coco Coir with High Frequency Fertigation” and “Understanding EC, PPM & TDS for Growing Cannabis”. The increased water that is taken up by the plant and the increased evaporation causes the EC to rise between fertigation events. Every working meter should get a reading of EC 1.0 from this solution . Source: Just 4 Growers: Global Garden Community i like reading posts from SCMC as he definitly knows what he's talking about. © Copyright 1999 - 2020 Grasscity.com is a part of, (You must log in or sign up to post here. Growers should avoid using coco-specific nutrients when amending coco with Perlite to keep plants from yellowing and under-performing. Log in or sign up to leave a comment Log In Sign Up. I'm on day 21 and plants are looking great. Discussion in 'Coco Coir' started by Budsmoker187, Dec 15, 2010. Starting with good quality (low EC) water is assumed. Different strains have different nutritional needs. Never use plain water in coco until the flush. great post! share. This is the PH buffer. Calculate your total adjustment, but if the total you calculate is more than +300, limit your actual adjustment to that. PPM stands for “parts per million” and is a unit of concentration. During the flower stage, optimum parts per million rises to 1000-1100. My combo meter uses a .700 conversion rate. Sounds like I've been running my PPM way too low. Water ppm readings have applications for both hydroponic and conventional soil cultivation methods. Use gentle lighting at 24 or 18 hours per day, and if cloning use a humidity dome to allow your young marijuana clones to take in water from the air until their roots form: For this reason, your main task is maintaining the run-off EC within the acceptable range. Let's say you have a solution with an EC of 1.0. My ph going in is also at 5.5. However, if it is not possible, you may need to lower the inflow EC so that the natural rise in EC does not cause damage to your plants. whats up dudes? The cyco kleanse may be fine but I have no experience with it. Coco coir retains water well — too well, if you’re a cannabis grower who tends to overwater. Starting water must be lower than EC 300. You probably want a PPM around 600. I've been pinching them out and lollipoping they now been in flower for 2 weeks. As water transpires from plants and evaporates from pots it causes EC of the remaining nutrient solution to increase. This means that when the coco has lost 10% of the water that it can hold you should water again. Start increasing your PPM by 100-150 until you reach a spot that is best. Santos L Halper Member. The EC that matters is the EC of the nutrient solution suspended in the coco at the root zone. Why do you suggest quater strength instead? In order to manage EC, you need to set EC targets for the nutrient solution that will be available to the plant. Slow the increase and allow plants to adjust. This causes the EC of the nutrient solution suspended in the coco to rise between fertigation events. However if you get a PPM of 600 and a pH of 5.3 you are on the borderline of poisoning the plant. Be patient if minor burn shows as you increase EC. But i get nute burn if i increase anymore so am i fine then? is it normal for coca to have such a high run off or did i mess up by not flooding my coca until the water ran clear. But yeah its the cyco kleanse not sure if youve heard of it but its mainly just citric acid and dextrose. I grow in 3 gal pots of coco. I found feeding lower PPM (in strain specific cases) that i was having more deficiencies . ). Advice/Help. I had no idea, ill try doing twice a day when the lights come on and see how it affects ph and ppm. Just as the nutrition needs of a plant change during its life cycle, its optimal EC range also changes: starting low, reaching a peak during late bloom, and going down sharply at the end. This now leads me to my true question. Thus, if your EC is 1: 1*1000/2= 500 ppm. You shouldn't worry about run off ppm, that's just a combination of the ppm you put in and the extra salts you flush out of the soil. By Volume of Water Needed: Coco mixed with perlite has the ideal air to water ratio when it is 90%-100% saturated. If you are growing a plant that prefers lower nutrition, then you may want to lower the target and maintain EC in a lower range. However, tap and well water may be used if they start less than EC 300. Tonight runoff came out around 1150. When considering the target EC for your nutrient solution (inflow), you need to understand that the EC will rise between fertigation events. PPM Levels for Cannabis Plants. Attached a pic cheers. hi growers. Water that starts with an EC of more than 300 should not be used. The first test we ran 500 ppm and 5.9 ph through the coco. PH is a concern though, unless you're running coco it sounds like you're a little low. Start with the LOW end of the Recommended EC/PPM Range. The general ranges provided above are appropriate for General Hydroponics Flora Series. In particular, you should avoid nutrient lines that recommend high EC ranges and frequent flushing. If there are any signs of burn, and the run-off is not significantly higher than inflow, then your target EC range may be too high. At this point you are ready to determine your EC range targets for each stage of growth. COCO ph and PPM questions. Nutrient companies should provide you with both a set of recipes in a feed chart and a set of EC or PPM ranges for each stage of growth. Do you put that kleanse stuff in the nutrient solution or do you just mix it with water by itself? As described above, water is removed through transpiration and evaporation faster than salts are removed. What should my PPM be? I grow in coco so I can see how they react within a day or 2 normally. who ever says runoff #s with coco mean nothing knows nothing about growing with coco. But how can you determine the dryness of your coco coir? Remember that the run-off EC is the value that you need to control. Heat and low humidity increase the rate that plants draw in water through their roots. My tap water is `120 ppm, out of the faucet. It seems that Greenleaf Nutrients Mega Crop has enough of both and if you’re having calmag deficiencies, you can just raise your dosage of MC (GRADUALLY) instead of … Both heat and low humidity also cause increased evaporation. You can convert back later if needed. We have a wonderful community of growers and you are welcome to join! To determine the correct adjustment for your particular grow, use the following process: You may or may not be able to use untreated tap or well water to mix your nutrients. If you use tap water, your reading should … This should be rare, and it might indicate some sort of salt buildup at the root zone. You want to "balance" your soil, that means what goes in should … my plants are 16 days old and I'm using canna coco with 10% perlite canna a+b 1/4 strength. I realize there are variables but looking for a basic explanation of how things “should be”. If you’ve really fucked things up with the pH in your coco substrate you may need to take more decisive action. Be sure to read our tutorial, "EC/PPM Targets for Fertigating Cannabis"The doses for the base nutrients (Flora Micro, Flora Gro, and Flora Bloom) are about half the dose that General Hydroponics recommends in their feed chart. However, if the supplier recommends EC ranges that are significantly higher than these general EC ranges, I would recommend finding a different supplier. You need to start by setting a target inflow EC value, but your real goal is keeping the run-off value from exceeding the maximum. My nutrient feed chart for the General Hydroponics Flora Series nutrients is provided. It is a great way to share your experience and ask questions along the way. If the parts per million reading is higher than 450 ppm, and/or the pH is wildly out of range, repeat the experiment to see if you can get runoff water that’s less than 450 ppm and within pH range. If you get a mix that has an 800 PPM and a pH of 6.0, that is fine. Ph should be 5.8 – 6.0. That's the only reason I suggested the 1/4 strength nutes for flushing. So from now on I feed my base nutrients at full strength (4mL per liter) and use my other nutes at 1/4 to 1/2 depending on how they look. Ppm going in is 750. You need to be able to measure the EC of the run-off from each plant. Since water is about half the total volume of saturated coco, the amount of water required should be about 5% of the container volume. Plants that size should be fed and least twice a day to at least 20% run off each time. I only put very min amounts of nutrients and always water in between.. they were definitely in lockout and I needed to remove the salts so I used florakleen and flushed through. Copyright © 2020 Coco For Cannabis Inc All Rights Reserved, Growing Cannabis in Coco Coir with High Frequency Fertigation, Understanding EC, PPM & TDS for Growing Cannabis, How to Manage Cannabis Fertigation by Measuring Run-off EC/PPM, How to Water Cannabis Plants in Coco Coir. Always 1/4 strength nutes or some sort of a tea with nutrients for a flush. Checking with the breeder information is best, but as a general rule: Always “listen” to your plants! I'm 12 days from sprout and the leaves on the 2nd node are looking pretty wavy. It happens fast. PPM is Higher in your Runoff than Sump. The Science and Practice of Growing Cannabis. report. Ohh seriously? The PPM hardness of your base water determines the PH of the medium runoff. I wouldn't worry about the ppm's but the pH is a problem. Inflow is added at the bottom of the range and run-off is kept from exceeding the top. Lower inflow EC until you can maintain run-off EC in the appropriate range. The ideal pH for coco coir cannabis grows is between 5.8 and 6.0 in the vegetation stage. Additionally, a 50/50 blend of coco fiber and Vermiculite is excellent for rooting cuttings and helping seedlings get off to a promising start, as Vermiculite clings to moisture, nutrients and a little air at levels that can be beneficial to young plants. I've been feeding them PH 5.8 tap water … If you ppm starts getting to high and your ph is dropping to low, it's time for a heavy irrigation of 1/4 strength solution to 'flush' your media of the accumulated salts. We also have a live chat room, which is a great place to ask questions, get quick answers, and chat with fellow growers. I feed at 5.8 and the run off has been 6.5 give or take a point. Long story short, check your run-off at least once a week to make sure your within range.
