What kinda light are you using? And how close is it?

And if you really want to know the leaf temp you can always get an infrared temp gun for pretty cheap. But it's not necessary.
Led light, about a foot away but my plants grew alot the last cpl days so it was a little closer then a foot.

Are you sure its a light issue?
