Sorry forgot to quote you.
. Run off ec is 1.5 after going in at 1.7 (healthy roots right?) , . I'm so confused. It's worth adding my tap water sits at .5 EC by itself. This is my 3rd attempt at coco, got a really bad broad mite infestation, decided to go with Coco after that, I haven't had a successful grow in 2021, I don't know what's up. Ten years straight without throwing out a plant, 2021 can't get threw veg. Do you mind if I ask you your nutrient regiment? I was thinking maybe I need one built for coco?
You should be feeding multiple times a day to runoff in coco. No straight water.

EC 1.7 seems rather high.
I’ve never been as high as 1.7EC.
questions.
1. Why aren’t you adding equal A and B? Normally you use equal parts of A and B with 2 part nutrients.
2. why arent you feeding every day?
3. On your next feed can you collect the runoff and test it’s EC? Don’t worry about runoff pH just let me know the EC.
4. I know you said environment is acceptable but what are the variables?
humidity is around 60 percent, heat stays from 75 to 83 F, light is a Mars hydro (the one built for a 4*4). I only cutt out .5 of the 16 B to try to get a little more nitrogen and cal mag in there (the heavy 16 bottles say 8ml per gallon of A and B, I can't even get 4ml in it without the EC going over 1.
Here’s everything I use and the EC values I use along with approx feeding amounts per day.

Just some helpful advice, don’t treat coco like soil. Coco is closer to hydro than soil. I have made all the mistakes when first starting out with coco. At that size plant feeding once a day is fine. You will start to notice the coco drying out faster as the roots grow, that is when you want to start bumping up your feeding. You do not want the wet dry cycle of soil with coco. You want to keep coco 90% saturated at all times for fastest and best growth. Every time you feed the water actually draws oxygen into the coco. If you let coco dry out you will start having issues from salt buildup.
Did you have it in 2 gallon right from the start ? I got these in 1 gallon thinking of transplanting to 2 gallon I just flipped 12/12.
Idk bud. I've been a soil grower for a decade, never had a failed grow. I can't seem to get this right.
Yes, I have 1 in a 1 gallon and 2 in 2 gallon smart pots.
If your looking for good nutrients for coco I would recommend jacks 123 or green leaf nutrients Mega Crop. Both are dry nutrients and super easy to use. Plenty of posts to show off how good they are.
So switch to distilled or ro or drop the cal mag from the tap water?
Hmm, I have yet to run into any cal issue ph'ing in that range. In fact, you can easily do a search and find that many others ph that high and has not had any issues doing so either.
Well shit man,coco should be a walk in the park for you.Your pots elevated? Runoff cant be allowed to suck back up.
Small Dixie style cup then into the 2G and then automated that.
I’d say stop using the Calmag if your source water is 0.5EC
