actually...on these two plants...I cut the colas off at 11 weeks flowering and let the rest of the plant go another two weeks!

THIS....was a waste of time!...(for me). There was No increase in amber % during those two weeks and no additional growth.

Bottomline: when the plant stops growing...the amber % increases very, very slowly...IMO....(and all the fan leaves fall off)

Most senior growers prefer 5-20% amber...max.
