Trimming

I am about to enter floweing with very short plants and my lights aren’t the best they are supposedly 1000w blurples from kingLeds. I have 3 plants in a 2x2x4 and the leaves started overlapping, If I cuut the bigger leaves, will it affect the plant a lot?

I sog clones that are much smaller and have no problems. Once your flip to flower they will get plenty big. Keep the big fan leaves on as long as possible, they help grow healthier, stronger stems.
