For this reason, your main task is maintaining the run-off EC within the acceptable range. 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! Log in or sign up to leave a comment Log In Sign Up. PPM stands for “parts per million” and is a unit of concentration. If you are growing a strain that likes “high nutes” then you may increase the inflow target, and work with a higher range. Growers should avoid using coco-specific nutrients when amending coco with Perlite to keep plants from yellowing and under-performing. If you get a mix that has an 800 PPM and a pH of 6.0, that is fine. If you are looking for advice and support throughout your grow, we encourage you to start a Grow Journal in our Grower's Forum.

But yeah its the cyco kleanse not sure if youve heard of it but its mainly just citric acid and dextrose. The lower the initial EC the better. When calculating your target inflow EC, you need to start with the low end of the recommended range. You should also be using a ppm meter to measure total dissolved solids while you’re measuring the pH. You should start by checking run-off daily until the numbers become predictable to you, at which point, you can skip days. Do you have a closer pic of the leaves. so i have tried to google my questions but not many clear answers. Can you take a closer pic of the leaves?

If you are starting with low EC water, the bulk of the EC will come from the base nutrients. Running autoflowers, medium Happy Frog soil, fox farm nutrient trio and call mag. share. I read somewhere else the ppms are low because the nutes are being used up? The increased water that is taken up by the plant and the increased evaporation causes the EC to rise between fertigation events. As water transpires from plants and evaporates from pots it causes EC of the remaining nutrient solution to increase. Slowly run 2x to 3x your container size of plain pH’d water to really flush it out. keep flushing until your run off ppms are very close to input ppms. *EC units are expressed in microsiemens. 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. 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. Ph should be 5.8 – 6.0. When calculating your target inflow EC, you need to start with the low end of the recommended range. As described above, water is removed through transpiration and evaporation faster than salts are removed. Was told to not even start Nutes until week 6, wanted to know what I want my feeding schedule and PPM. So if I want a ppm of 720, I set it at 840, ...

However, natural PPM is 350 out of the tap. If you are unable to fertigate frequently, then it will be harder to maintain a tight range between inflow and run-off EC values. If so, that could be a problem. Ppm going in is 750. However, if the supplier recommends EC ranges that are significantly higher than these general EC ranges, I would recommend finding a different supplier. Plants that size should be fed and least twice a day to at least 20% run off each time. The run-off EC is the best proxy for the EC of the nutrient solution in the coco. Budsmoker187 Registered User. 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.

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. However, tap and well water may be used if they start less than EC 300. 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. We used a 1 gallon pot of coco for each test. Not sure how much cal mag I should add to the fertigating water. 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. 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 … 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.

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. In particular, you should avoid nutrient lines that recommend high EC ranges and frequent flushing. PPM is Higher in your Runoff than Sump. Heat and low humidity increase the rate that plants draw in water through their roots. 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. 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. The PPM hardness of your base water determines the PH of the medium runoff. When considering the target EC for your nutrient solution (inflow), you need to understand that the EC will rise between fertigation events. 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. Start with the LOW end of the Recommended EC/PPM Range. If EC or PPM ranges are not provided, you should use the general ranges recommended above. 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. However if you get a PPM of 600 and a pH of 5.3 you are on the borderline of poisoning the plant. COCO ph and PPM questions. Depending on your plant’s maturation and the number of nutrients it can absorb, the ppm should range from 750 ppm to 1500 ppm. Therefore, the target for the EC of the inflow is always lower than the maximum acceptable run-off score. The EC that matters is the EC of the nutrient solution suspended in the coco at the root zone. See our tutorial “How to Manage Cannabis Fertigation by Measuring Run-off EC/PPM”. Calculate your total adjustment, but if the total you calculate is more than +300, limit your actual adjustment to that. I've been feeding them PH 5.8 tap water … Start increasing your PPM by 100-150 until you reach a spot that is best.

You definitely want a pH between 5.8 – 6.3 (Lower for hydro, higher for soil). PPM stands for “parts per million” and is a unit of concentration. 2 comments. 400 microsiemens = 0.4 millisiemens. But … It is set for the standard EC targets, with no grow specific adjustments. 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? 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. Coco coir retains water well — too well, if you’re a cannabis grower who tends to overwater. I realize there are variables but looking for a basic explanation of how things “should be”. 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. Around 400. You can convert back later if needed.

Be patient if minor burn shows as you increase EC. save. In order to manage EC, you need to set EC targets for the nutrient solution that will be available to the plant. In the chart below, you can find general guidelines for optimal EC at different life stages, however, there are differences between different nutrient lines. I suggest you flush with 1/4 strength nutes instead of that clearing agent. It's hard to tell with the yellow HPS light but your leaves looked striped. My solution going in is around 750ppm, but im using cyco so apparently that's equivalent to 1100 or so ppm.

I grow in coco so I can see how they react within a day or 2 normally. And if your ppm is 500: 500*2/1000= 1 EC . Therefore, in addition to lowering inflow EC, you should also increase fertigation frequency. 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. my plants are 16 days old and I'm using canna coco with 10% perlite canna a+b 1/4 strength. 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. who ever says runoff #s with coco mean nothing knows nothing about growing with coco. Remember that the run-off EC is the value that you need to control. My combo meter uses a .700 conversion rate. Always 1/4 strength nutes or some sort of a tea with nutrients for a flush. When considering the target EC for your nutrient solution (inflow), you need to understand that the EC will rise between fertigation events. Thus, if your EC is 1: 1*1000/2= 500 ppm. The cyco kleanse may be fine but I have no experience with it. 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. If you are using reverse osmosis water, the reading will be 0 to 10 ppm as it is completely free of minerals. 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. hide. This causes the EC of the nutrient solution suspended in the coco to rise between fertigation events. With soil cultivation, the water ppm should be checked after adding additives to the watering vessel. report. That's the only reason I suggested the 1/4 strength nutes for flushing. We explain the importance of EC in “Growing Cannabis in Coco Coir with High Frequency Fertigation” and “Understanding EC, PPM & TDS for Growing Cannabis”. You need to be able to measure the EC of the run-off from each plant. But how can you determine the dryness of your coco coir? 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. 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. 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. The only reason that I suggest 1/4 strength nutes is because I know there is no risk to the 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. Listen to your plants! I wouldn't worry about the ppm's but the pH is a problem. i like reading posts from SCMC as he definitly knows what he's talking about.

Long story short, check your run-off at least once a week to make sure your within range. This should be rare, and it might indicate some sort of salt buildup at the root zone. So I flush with 300ppm 6 gal of solution per plant, checking ppm run off at 2 gal, 4 gal, and 6 gal. I am currently in my 4th week of flower and I think I may be seeing signs of potassium deficiency. 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. Could someone PLEASE help me understand. What should my runoff ppm be in soil? I hope this issue works itself out. This means that when the coco has lost 10% of the water that it can hold you should water again. Every working meter should get a reading of EC 1.0 from this solution . Lowering the EC makes it easier for plants to pull in all the water that they need. 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. 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.
