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.

I would love to help you, but I'm actually having the same problem. I'm wondering if I have maybe too much Nitrogen and too litlle phosphorus and Potassium. However, since it's your fifth grow, you probably know this already.,,

If you are running co2 be sure it is vented before the hps goes off. They breath oxygen when the lights are off.

I got bored of opening my tent to see very little growth 6wks into flowering so i put my plant (only have one) in the bath and gave the soil a good flushing with the shower head. This may not be a time tested practice and i may get slated for suggesting you do this but it helped my grow no end and the plant took on a new lease of life!!
