Hello all, I'm growing indoors in a 2x2 grow tent I made, with an LED grow light. I'm questioning my setup. It gets about 88F in there and I have no fan. Should I add one? My Habanero plant started off great, but now the upper leaves are much smaller than the leaves at the base. It's flowering, but they bloom and fall off. It also drops lower leaves here and there. The upper leaves are a much lighter green. Is it too hot/stagnant air or would there seem to be a nutrient deficiency?
