I'm a big advocate of letting those starch and sugar factories stay on there as long as they will, fan leafs creat starch and sugars, which in return creats big buds, you need these for max production, you can tuck them under or tie them back. do what you can NOT to remove them getting light to the leaf isn't as important as what the leaf gives the bud, try briging the buds forward and tucking the leafs under, you can eaven bunch them and tie them to your stake, just dont snap the stems.
