Those big wide leaves are what turn the light into bud they are solar engines and the more light they get the bigger the plant will get and in the end the more buds you will get. Tying them down or removing them defeat the reason that the plant grew them........are you smarter than your plant? Train the growing tips to spread out by bending and tying so that you have an even height canopy so more light will hit the plant you can use netting or do a search on scrog.
