If your lower leaves aren't getting much light, you can chop them off to allow the plant to better manage it's limited energy on the bud production of the canapy. But be carefull and ask an expert because I'm not sure how violent you should be! If you snip the wrong branches you might hinder the plants abillity to capture light by robbing it of important leaves!

Also by only cutting half of the leaf first ,and then cutting the whole leaf a few days later you will reduce the overall "shock" to the plant .
