Yeah no need to top her(hopefully). Just by bending the main stalk for a few days you will make the plant branch. And you should end up with more when you harvest. Bending the top and allowing the other branches to catch up will allow for a more even canopy. And as long as you pull the lower growth on the branches at flower time the energy will be concentrated toward all of the branches tops. Leave the fan leaves but pull the growths. They won't end up getting much light so its all popcorn buds and energy that could be used elsewere.
