yeah man, too early for nutes, and be careful with watering. since your using LEDs, the plants sweat WAY less, and the soil temp doesnt rise much. the drooping is prob just over watering. happened once with mine, but soon as you see how much water they like, they are fine. the plants will use prob half the water as they normally do.
and good luck with the china panels. told ya we got some before the procyon, and they were crappy. we got them off ebay, from the same people. just trying to help man.
