Yah, your in the danger zone with those high temps.
Your plant shuts down. as mentioned depending on the Humidity your plant will close the stomata stopping transpiration (water up take)
Your soil over time gets warmer, and warmer until it becomes a problem to the plant too.

Good Luck on Your Grow.

Fans
A/C
exhaust fan - exchange the air in your grow space.
Try running your lights at night when the temps are cooler.

It can be hard to get those temps down.
You run the risk of stressing the plant. sometimes they hermaphrodite from the stress.
