Bloombox First Grow From Seed

compared with the pots, one's being kept at 5.8Ph daily and the others just watered once a week.
If you are treating your coco plants like they're in soil, that is probably what's wrong with them.
Coco grows are hydro. You need hydro pH ranges and hydro nutes. pH 5.2-5.8 has worked well for me and colleagues.
Coco is intended to be watered differently than soil. Soil needs to dry out a bit between waterings--coco doesn't. In fact, if you let it dry out just a bit too much, your plants won't recover. Coco can be watered every day.

Some updates...
Killed the two in the coca, moved the best 9 into flowering, 3 remaining are still in the veg side hydro. The plan is to take clones off the best two or three as soon as it's possible to tell that they are female. Then move those newly named mothers back into veg side (coca) and replace their flowering spots with the ones currently left behind. I'd like to take 20 cuttings if possible, and have the moms rebound in 6 weeks.
