Well I wasn't planning on topping it, the stem broke accidentally.

As for the leaves, I over-fertilized them & they got nute-burn, so I flushed them & they've been recovering. What exactly do you mean by "the light is burning through them"? Should I put them into something more opaque, you mean?

I know this is a half-assed attempt, but I'm living at my girlfriends for now & didn't have the means to set up a growroom here, & didn't wanna run up her electricity bill. I'm just hoping they do alright for a week & a half until I can get them into a much more marijuana-friendly envioronment.
