The leaves near the top of one of my plants are curling upwards, picture shows what I mean. What could cause this? I think this plant also has an N deficiency, so could this also be a symptom of that? pH of the water is at a constant 6-6.2, just watered for the first time with molasses (1 tablespoon/gallon) yesterday, using FFOF soil, this is day 36 of the plant's life, plant is about 1 inch from the CFL setup. If any more info is needed, just ask.
