8 to 10 weeks is about all you get during flowering i would say your close to being done
Didn't he just say he did and they are turning amber? I guess that that's not the main cola in the pic. Is it? that bud could use some fattening up for sure (they always can! lol)... but can you tell it's small just by that one pic?are you still adding nitrogen??? if so stop and its magnesium deff and i wouldnt harvest yet still lookin small, get a microscope n check out the trics see if they are cloudy
