The h2o2 isnt super necesary it more like a prevenative against root problems. Once per change.

I think you are doing real good so far :thumbsup: plants look healthy, good color, standing straight and all that crap The drooping thing is most likely just the plant wanting light. You said you are turning lights off so I guess your running 18/6. It will grow out of it. The leaves on a plant are like solar panels. They recieve the light energy for the plant and also store "extra" energy for dark periods. Small plant doesn't have big storage so not enough energy to keep plant happy till light. Hope that makes sence cause I think I just confused myself :wtf:
