Let it go now just wont be as plentiful as say 30 days but I have heard the pros say OK after root. Are they clones or seed? Doesnt matter I dont guess. Indica or sative and what is flower period for your strain...you have 10wks

they are from seed i have three afgan kush and four opium(50-50 sat ind) the kush is 8 weeks and opium 60 days.i have used professional grow soil and kept a strict ph of 6.5 with an electronic pen.on my last grow i didnt get this sort of growth after 5weeks.
