Well that's the thing, I am using only Palm Springs area sunshine (strong) and the fan leaves towards the bottom were cupping and turning yellow at tips, so I clipped them. I have been flowering for 45-50 days with 12 hours of uninterrupted pitch black. The wild white hairs are now forming into a mass of crystals and more buddage seems to be occurring. As you can tell, this is all a learning experience for me, and since October I have become addicted to this site. The more I learn, the better off I will be next time. I plan on learning more about indoor growing so I can supply myself.
