Yellowing Tip

Hey, ive got some little guys about a week old under like 5 13w cfls. The metal lampshades might have been touching the leaves of the plants, but im not sure. Anyways now one has a little yellowish-white splotch on it. Should this anything to be worried about?

looks like a heat burn back your lights off a bit...it'll get better.

Looks like your light got it....just be careful.....

thanks man. You know, just worried about they kids.

nothing to worry about. just watch the temp. high temp also leads to other issues, humidity mainly.
