Thanks Muddy, I have started to remove some of the yellowing leaves however I've been using nitrosym throughout flowering 2ml per 2.5 pints, done this for the last six months which has always kept everything nice and dark green, I agree to much isnt good for flowering but most bloom lack N, I'm currently mixing plant magic organic with biobuzz 50/50 (not together) this time round, maybe the high levels of N are prolonging flowering as I have never waited this long on ak47, she on pure water now till harvest, 90% of pistal s are still freash looking, so yeah two weeks.
Noticed no leaf mutation this time but a hell of a lot more buds sites at the bottom.
Any experaince with ak47?
