Heat is definitely a factor in the plant. Can you use AC in the lung room? Pictures are best taken with the grow light off and use your camera flash.

Definitely heat
The curling leaves is the proof.
Use a fan directed at the plant and keep it running/make sure your light isn't too close and you should be ok.
