don't ever remove fan leaves before harvest for several reasons.
1. The fan leaves convert and store more energy for the plant than any other leaf. The more energy the plant generates the healthier the buds that is just millions of years of genetics at work.
2. Even if the fan leaves are yellowing in late bloom I do not remove them until they are almost ready to fall off. The yellowing in the fan leaves at late harvest is the plants metabolism at work. She is transferring all stored energy in the fan leaf to bud production. It is the easiest source of energy she has late in life. Once again millions of years of genetics can't be wrong or we wouldn't have weeds to grow now. https://www.rollitup.org/general-marijuana-growing/newreply.php?do=newreply&p=32792HYPERLINKnewreply.php?do=newreply&p=32792
