3 diff plants finishing week 8. Took leaf cuts close to top buds. The buds look like they need a bit more time in my opinion, but without you looking at plant trichs are showing peak?
show us a picture of the whole plant or a bud site? those trichs looks like they need more time imo.
how long have you been in flower? are these autos or photos?
Trichomes on leaves are not a good indicator, when all of the white pistils have changed color and receded it is time to scope the trichomes on the buds themselves.
Breeders times are only a suggestion and likely under ideal conditions, they need to go as long as it takes !
