I don't see why you couldn't pull a few leaves. Don't go too crazy and they should be just fine. They'll grow more real quick. You prolly wouldn't need to take but a few on each plant to tidy things up. Main thing is don't stress yourself about it. I was real nervous at first too but they're resilient plants, and you only get the hang of it by doing it. I had to take some off the bottom of a 5 wk old today because they were laying on the fabric bag and getting wet and unhealthy looking.
They're looking great. You're gonna have a bunch of flowers soon.
