Hey guys these are my plants after about 3 1/2 weeks under light. I had them on a 24 hour light schedule and was watering daily until I figured out that was bad. Now they are on a 18/6 cycle and I water maybe twice a week. They are in MG organic potting mix. I take care of them I just dont see why the leaves are brown and crusty some have even fallin off. I sprayed them for bugs 2 weeks ago organic plant safe spray. I water them with distilled room temp water. They have a fan blowing on them constantly. I just dont know what it is. Maybe I need some nutrients or something idk.. anyone please help. Thanks!
