if i was you i would transplant into a slightly larger (deeper) pot, cut the 2 bottom leaves off and repot so the soil is about an inch from the first set of nodes. buy some new light maybe a 250hps, this would give your plant more growth in veg and in flower (bud production). get some nuets canna is easy to use, feed 1/4 strength until you get a run off. if you are in soil water when pots feel light, if you are in coco run to waste every day. water early in the day about an hour after light comes on. also noticed some water on leaves try not to get water on leaves, this acts as a magnifing glass and burns leaves if you foliar do this just before light off.
