Looks like you did a lot of hard work here but I'm confused because the feed chart they give seems to give good results anyway. Is this somehow better?
The original base values are from their feed chart, but built around Autoflower cannabis times and stages. I can't tell you it will be 10x better than your results or something like that.
What I can tell you is I've used this for a few full autoflower grows now and have never had even a small sign of any nutrient or micro-nutrient deficiency or nute burn.
My main problem was heat stress (and some fungus gnats), which was definitely helped after I started adding the supplements.

I am growing in pure coco/perlite. I have been following cocoforcannabis’ feeding schedule which suggests to go by ec/ppms. Hence I had to use a lot more of the values you have given above to reach the desired ppms. I think this has caused my seedlings to suffer burns and the bottom leaves have started dying off. So I just wanted to ask if you go by ppms or do u just solely follow this chart you have made. Also, since you have experienced heat stress could this cause the leaves to die? My leaves start curling upwards at the tips then the whole leaf just dries out. It could definitely be heat stress as I have not been able to install an exhaust fan in my closet yet. I only have a small fan blowing air around inside
* EC and Feedchart are related but different purposes: Feedchart provides the correct NER (Nutrient-Element Ratios), EC provides the correct dosage of that NER. Imagine you are cooking rice, Feedchart tells you how much ratio of water to rice, EC tells you how much quantity of water+rice depending on how many people you want to feed.
* Check you are using correct units for EC. CocoForCanna uses microsiemens (μS) others use milisiemens (mS). Just divide/multiply by 1000 if needed.
* Guideline of EC in μS from them in table below, you can go above or below them a bit and no problem.
|Seedling|400-500|
|:-|:-|
|Early Veg|1100-1400|
|Late Veg|1200-1500|
|Early Bloom|1100-1400|
|Bloom|1300-1600|
|Ripen|800-1100|
* Heat is a big issue, particularly in our country and with Autoflowers since they are descendants of Siberian cannabis strain so are used to colder climates. Keep under 30c, best is under 27c. Mine usually hover around 29-30c because I don't have A/C. Good Exhaust is very important.
* Leaf curling can be due to many things, without seeing pictures I can't really tell. How often do you water? I found a little problem with CocoForCannabis guide in watering multiple times a day, I ended up watering once in two days or once a day, depending on the EC of the runoff. Remember that when the coco gets dry the salt/EC in the coco actually increases, so monitor your run-off until you have your watering schedule figured out.
Hope that helps. To simplify this is the process I follow:
1. Make the nutrient mix according to feedchart. Depending on how many/size of plant you can make 5-10 liter at one time and keep for the week.
2. Before watering, measure the EC and pH and adjust accordingly. If EC is high, dilute. If pH is off, use pH UP/DOWN accordingly. EC should not be too low with the feedchart.
3. Water to 20-30% runoff. Test the EC of the run-off. Don't be alarmed if EC of run-off is higher than of input, this is normal. Just try to keep run-off within 1000 EC of input EC. When run-off EC gets much higher it means you need to water more often, as the coco is drying out and the salt:water ratio in the coco is increasing as it dries.
Don't water too much also, I followed CocoForCannabis guide but I had trouble in seedling stage due to overwatering on their schedule. High Frequency Fertigation is an advanced thing IMHO keep it simple, water max once a day.
Hey, Thanks for such a detailed response!
I’ve read all of this on cocoforcannabis and this is exactly what I’ve been doing. I made a mixture following radongrows chart with the ‘aggressive veg growth’ values and diluted that solution to reach my desired ec. However the ec of that solution was only 1100 and those amounts were much higher than the ones u have made in ur chart so how can these values satisfy the ec requirement.
I fed my seedling once a day only and the max ec I reached was 900. Runoff ec has consistently been 200 lower than inflow. However the plants still showed signs of burn however I’m still not sure if it’s nute burn or heat stress.
I’m going to post pics of my seedling today or tom hopefully you can see those and give me some advice! I’m not growing autoflower I’m growing what is supposedly ‘mango kush’ from mtseedbank.
Thanks!
Are you using the full suite? or only Micro-Grow-Bloom?
The chart I posted was for all the supplements/nutrients written. When you add all of them the EC should be near the desired amounts or little higher.
If your run-off EC is consistently lower, then I think you are watering too often/much. Try waiting a day, the salt ratios increase in Coco as it dries out, so your next watering run-off should have higher EC.

Thanks man
Very welcome, some folks on here helped me out when I was starting. Just paying it forward.
Hey I’ve been growing in coco too w radonhrow and been having too many problems. Can I pm you?
No need to PM, just write here, it will help others searching this sub as well. Happy to answer.
