Me and my roommate are growing a single plant for ourselves just for kicks and giggles, and we're completely new at this whole thing. So far everything's been going smoothly until a couple of days ago when we noticed that the light (CFL) fell a few inches and started touching the leaves to the plant and caused minor burns to a couple of leaves (pictured below). The light is moved back to the original spot, but does the burnt part of the leaf have to be cut off or anything? Also are there any suggestions to prevent this burn from happening again?
