First Grow

Think I'm doing alright, there healthy and bushy. I've topped them twice so far and been doing lst. Snapped 3 mains trying to use the clips but looks like i saved them using (none wilted as of 4 days)I think I waited too long to use them as the branches are very tick. I've used silica every other watering. Also I just raised my light so there starting to stretch a bit. There nutes are gaia green and I hit them with recharge once a week. Idk let me know your thoughts I would appreciate any advice.
