There's been no male's near them mate.. She is in her 5th week of flowering. And the rest are in there 3rd week. al hairs have turned brown on this 1 but only on top. the one's at the bottom are just starting to turn brown. im bit worrried after al this time as the tip's of the leave's are starting to turn white too, Do you think it wound be worth while giving them 1 flush with bloom.
