I use the dark period to force the plant to use up the rest of the nutrients stored. If a plant won't finish, it'll get a fresh watering and then stick in a dark room around 75F with 20% humidity to help dry the pot out. It in some cases makes plants a little frostier in the sense that the trichomes do get longer. Not grow more trichomes.
It's all good with the nanners since you caught them in time! In 2 weeks the plant could stop bud growth to the effected areas and start forming little premature seed pods. They would be significantly smaller than a seed but still pop when you smoke em. Nothin too bad ya know? I'm very proud of you man, this AK-47 is way better than any AK I've ever grown. If I ever come across seeds of it, I'm coming to you for the low down.
Much love and respect.
