I'm afraid I'm having trouble following the thread....and I can't see any sort of flowering on that plant either. It does seem that you need better lighting or soil or both....for 7-8 mos it doesn't look very big. I realize you are experimenting but I suppose my question would be....why? I think that is what is confusing Mark as well.

Most of us grow for really one reason.....to get excellent smoke so there is no experimenting involved....we grow the quickest, fastest, best way with the quickest and best lighting, nutrients etc. That is why I say your thread is confusing me.....I'm not sure what it is you are trying to accomplish with the experiments.
