Plant welting with light on

Hey guys

My plant has started welting the last few days whenever the light is on... the temperatures are a steady 82-85 with the light on. During dark time it perks right up but then after I turn the light back on the leaves all welt down

maybe it might be too hot in the room?

A ton of variables for you to list but the pot size vs. size of the plant would be a good starting point. Age of plant, growing media, type of light, spectrum, distance from leaves and on and on....
