Hi there, out of curiosity, how close did you have your lights to your plants? You don't need to throw away your lights, but you do need to back them up, your babies are cooking. It's hard to overwater plants in coco especially past seedling stage but you do want wet/dry cycle to promote strong root growth. Feet wet/ankles dry. I suspect your lights were extremely close causing the bleaching, curled leaves and leaves being dried/crispy. I would disgard any damaged/burnt leaves, ensure good air flow around canopy. I usually start my LED'S 30 plus inches away while slowly lowering 1 inch per day until you reach your sweet spot. 15-18 inches is prime for the lights that I use but yours are different so you have to observe each day to how your plants respond. Listen to what your plants are telling you, in this case the leaves are curling upwards and are crispy as chit. She's trying to say she is way too hot. Your stems are most likely red because of the light stress. PH could be lowered a tad 6.0- 6.3 but otherwise I believe the culprit is lights to close. I hope this helps you. You've come to the right place, best of wishes, Stalks Strong!!
