That looks like a pic on a sugar leaf
To be honest. If so, definitely start flushing if you havenāt already (if you practice flushing). You should be looking like 90% milky on your buds at least by this point. Iād say you can harvest anywhere from now to a week from now and youāll be lore than happy. Donāt forget an extended dark period has been known to help develop richer profiles in the buds as well.
Happy growing.
