Only if they are getting yellow! Fan leaves are the "food factories" for your plant. Removing them cuts the amount of nutrients your plant gets! Granny
only leaves you should cut are the small ones, that are all on the bottom. you would want to remove them because 1. they will eat up your energy 2. the energy that's going to them wont be as good that's going into your bud production 3. once those are removed, no more energy is going to those little leaves, but instead goes right into your buds. if you follow what im saying. maybe i wrote it wrong. but look up lollipopping .
p.s. this will help you with everything. you still have time to chose a method. http://forum.grasscity.com/indoor-m...training-scrog-sog-fim-supercrop-lst-etc.html
i just trimmed mine and they seem to like it. I only cut the lower level of leaves that were not getting light and they were smaller than the rest of the plants
