lol, there was some guy here that mentioned that males have a certain smell and ive come to find its true.
quite distinct from females.
id check for that, not looks, as sometimes females can look very male.
was absolutely sure on one, totally looked like a male, so i cut all the small leaves (desperate for smokes back then)
but a week later it revealed itself as a female, (lucky i didnt throw it away, eh?)
did have to put it into reveg though. cause i cut all the small leaves.
