heres what i saw "bricktop" post a while back, and have seen these kind of facts posted alot of times so no you should not trim your plants, the only trimming that should be done is when you have harvested
Fan leaves are the largest most efficient solar collectors plants have. They absorb the largest amount of light rays and transform it into energy. Large fan leaves are factories where sugars/carbohydrates are created and stored for later use, as in for use during periods of darkness when plants operated on stored energy, etc.
Any healthy plant will attempt to replace any lost healthy foliage, until fairly well along in flowering anyway. When you remove fan leaves a healthy plant will divert energy that would otherwise be used for continued upward/outward growth, and when in flower for bud production and also THC production, and use it to attempt to replace the lost healthy foliage.
The idea of removing fan leaves is based in a flawed pseudo-logic. People assume a plant has X amount of energy to use and then assume that those large fan leaves have to use a great deal of energy plus they shade buds from direct light and of course people assume you have to have buds flooded with light. Well when you remove the healthy fan leaves the amount of energy plants had to rely on, X, is dropped to P. Then the P amount of energy is in part diverted to replace the lost healthy foliage and the rest of the plant then has K amount of energy to rely on for growth and bud development.
Many people do not realize the importance of fan leaves and they do not understand how plants actually work, what they do, how they react to different things. Something else some, or maybe even many do not know is that on average 85% of light that strikes a leaf passes through. On average a leaf will only collect 15% of the light that strikes it and again, the rest passes through the leaf to then strike lower leaves.
Do not remove large fan leaves unless you want to reduce your plants capabilities to function as they normally do.
