What's up broham! Topping is fairly simple, you want to pretty muach pinch the top of your plant after it has developed 4 nodes (branches). Be sure to spread the top leaves until you just see a little nub on top (new growth), grip tightly, and pinch. Now you'll have 2 main branches instead of 1. LST method is also simple. You just simple tie a string to the top 1/3 of your plant, and pull the branch down until it sits horizontally (sideways), allowing much more light penetration to the inner branches.
