Well the plant is already being "shocked" by the heat so u need to level the temp out, you need some air blowing directly to the plants it'll bring down the temps a bit for the plant.....
Last year i grew 3 plants in the summer in my small 5'x4x8' closet it was about 85 degrees in my room so it was pretty hot in the closet with all the cfls i had going about 200+watts i had two fans blowing directly at my plants which kept them at bout 80 degrees fans do make a difference. Add another one.
