You could..or you could top and let the bottom catch up to the middle.
I would encourage you to read a few threads on defoliation, topping, and training. Alot of good information/videos out there that might help you out. Defoliation is a debatable subject lol, be ready for posts to be all over the place. Try to filter out what applies directly to your grow set up and take things with a grain of salt.
Grant you only want to remove a few leaves....defoliation usually involves stripping alot. Searching those subjects will show you why people do remove leaves, what leaves they remove, and when they do it.
I personally top to get more bud sites, and defoliate/strip bud sites that wont turn into much. I do not do this not for the claimed "increase yeild" but more a preventive. Less leaves and uselss bud sites = better air flow, better light penetration and makes it easier to see more of the plant to keep an eye on deficiencies, diseases, or pets.
Happy Growing!!!
