How many weeks left for these plants?

check the trichomes. at the very least follow the breeders guidelines if you cant check trichomes.i believe this a 9 week strain so are you at week 6? id say give it another couple weeks. youll be happy to wait. the buds really ripen during the final weeks. the plant still has white pistils and there isnt any sign in the fan leaves of color changing which are both a signs to watch for if you cannot check trichomes. start flushing and wait. dont be overly impatient. its better to have if slightly over ripe than under ripe. theyll pack on weight in the next couple weeks.
