When trying to determine your harvest window it good to take a few things into account. First off breeders will say whatever time frame that they've determined under their ideal environmental conditions. Secondly, actual flower period doest start until buds have formed. The Stretch phase in preflower is considered part of the vegetation. So usually about two weeks from flip is when I start to count my weeks of flower. Now this gets you to the window, wide as it may be. You'll want to check trichomes to determine your preferred amount of amber to cloudy trichs. From the looks of it she's got a few more weeks left. At least another week before the pre harvest flush. I see lots of white long pistils on her, she's got some growing to do still
so do you think next weeks feed i can go (2ml bud candy-2ml overdrive-4ml boost-1.25ml pk13/14-cannazym)? and cut out a+b & b52?
then the week after flush with canna flush twice then the week after that just plain water?
thanks again stinky i will eventually learn, and your helping me alot with info!

pollination is the natural way these plants endure through generations. You can pollinate a single branch and have the best of both worlds. Good bud and some fresh seeds that'll be of like genetics. If you pollinate a plant by just having the male in tent together, then you'll have very little smokable buds but a massive amount of seeds. It's a project worth looking into...
