well... it's been 31months, so no worries nowto answer ur question man i dont know the exact amount of time but a week or two i would guess, if u did as u said (right when pistils showed) then it should be fine, but if u were a little late on that then it would take longer obviously
im wondering the same thing, i grow indoor but i put it back under 18 and 6 and its bin growing awsome BUT now 2 months after that the pistils that showed from when i sexed it are turning brown, so wtf does this mean? lol is my plant fucked now or will new pistils regenerate? ANYONE!?
