i am on my 5th grow now and i cut my lights back 16 days ago and havn't seen much flower production. i few white hairs here and there....its all in a rockwool hydroponic setup. i have a 400 watt hps in a 4x3x3 high room. i have seen nothing more than just a couple white hairs pop out per plant they have co2, 74deg F temp....water....60 % humidity but very slow flowering growth. Anyone know why they might not be bursting into flowering. if i recall correctly by the 2nd week of my last grow with the same strain ther were knotting up like crazy. if anyone could please help let me know.
