This is my first grow in coco and using the Green Planet dual fuel kit and Pro Cal nutrients, there is no perlite in these pots and I didnt know that you had to mix perlite with coco and I think they're over watered. Ive poked holes in the pots to attempt to get more air to the roots.
R-L Gelato, Gorilla Glue and Gelato, 4.5 weeks old.
Temperature 65 degrees, humidity 60%.
Ive read you water coco until it runs out the bottom which is what Ive done.
I want to transplant to 5 gal fabric pots soon.The new growth seems fine just the fan leaves aren't looking too happy.
How far do you go in drying out the medium for coco before watering? Ive got the heat mat running, is that ok at this age?
I topped the Gorilla Glue and the Gelato to the left 6 days ago and Ive read that sometimes top leaves will flop from stress after topping.

What size is your grow tent
Update, they've bounced back, low n bushy, lots of defoliation, some topping , lst, lost a main branch on GG4 (left).
Would like to say thanks Cam Z.
Thanks.
It's probably a combo. It looks like overwatering. You don't need to water until runoff every time but they'd probably be ok with it if you could get the temps up. I see 3 things working against you in your description. Too much water, temps too low, and rh too high for that temp. With too much water the plants need to transpire that moisture away from the root zone. The temps are too cold to allow that to happen. Further compounding the issue is a rh of 60. The plants can't push water through their stomata because there is too much environmental pressure at with that rh at 65. If you can get temps around 80 and keep the rh the same the plants should bounce back pretty quickly. I'd also hold off on the watering until you see a positive improvement imo.
