Leave leaves alone! Removal of healthy leave hacks up a healthy plant. Removing large or shade leaves DOES NOT make plants more productive. This practice DOES NOT supply more light to smaller leaves and growing tips. Plants need all their leaves to produce the maximum amount of chlorophyll and food. Removing leaves slows chlorophyll production, stresses the plant, and stunts its growth. Stress is a growth inhibitor. Remove only dead leaves or leaves that are more than 50 perfect damages.
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.
