First Grow (3 mixed Autoflowers, Indoor 2x2) Wish me luck!

This week started off well, I topped two of my plants, and they seem to recover okay, but then disaster struck. I was trying LST for the first time, but in my excitement I accidentally snapped two of the lower branches off. Not quite sure how big a deal this is, I hope she will recover and not impact my yield too much. Update: The girls grew nicely this week, however, I suspect I might have overfed them a bit. Especially the Super Strawberry Skittlez seems to be the most stressed, with some very dark and slight curly leaves. It's also quite bushy and compact, which makes me think growth might not be optimal. Hoping to get her back on track this week, and cut back on her feeding.
