Everything is looking good over here. As far as you trimming your leaves i personally was against it my whole grow. But ended up having to trim some leaves that got too close to the lights. You going to get different responses regarding the trimming some people says its ok and some people feel like it slow growth. You really going to have to make that choice yourself. But it's some really cool people on this site that may be able to actually walk you through which leaves should be trimmed if u decide to do it. As far as Topping being terrible i also have read that from some people that didn't do it the correct way. Topping is only good when its still in the veg stage and you still have to give them time to recover after the cut. Its hard to get 100% accurate advice when it come down to growing these plants. What works for one person may not necessary work for you. Just pay close attention to your plants and they will let you know what they can and can't handle.
