scousa theres been a few male pre-flowers appearing on 1 of my plants,i check it closely everyday and if i see any appearing i remove them with tweezers before they get the chance to develop.i noticed them on it about 30 days into flower (now 35 days) so the buds were already at a fair size so didnt want to destroy it.5 days after removin around 15-18 pre-flowers ive only removed another 2 since then,you might not want to take the risk but i decided to chance it,ill find out in a few weeks!!
