Looks like a few of them over watered hold off on watering the morevyellow droopy ones Coco dries out easily there for roots getting more oxygen and not having problems.Day 26 for these four they share the same light, a mixture of Coco Coir, Perlite, Succulent Mix is in these four im feeding them Aero Garden 4-3-6 and little bits of 10ml/g Vegetable Glycerine. I started these at 16" of this 99w light i realized they might be going through light stress so i upped the light to 24". Only Plant one is growing full green its in full Coco Coir. RH is like 50-60% Temperature from 72°-80°F
