With LEDs you want to keep lights closer to the plants for deeper light penetration. Are you running dimmers ? Crank it to 100% and clean up the canopy. Also for an area that size you may need stronger lights.

To make matters worse I also had an issue where the AC was out for a few days which resulted in high temperatures 90+. When the AC was fixed it somehow...
