Growing in coco perlite
I think we overwatered them and fed them too much too early. So we backed off and let them recover. Now the other 3 plants seem to be doing alright, maybe a little stunted. However, this one is worrisome.

Temp has been around 80 humidity around 75.

27 days old

nutes have now been upped slowly to 655ppm but just went back down to 600ppm today
Contents of feedings are about 250ppm calmag and the rest pure blend grow ph between 5.8 and 6.2
led lights 24 hours on between 500-800 ppfd

Run off has tested with lower ppm and higher ph than inflow.

first time grower, let me know if I've left out any important info!
