It seems to be overwatering, my friend. The heat usually causes the leaves to curl a bit like a claw, but if they are drooping like that and you've given it a lot of water, that's the problem. (Otherwise, as another member mentioned below, it could be underwatering, where the leaves also droop down.) But in your case, since you know you've given it a lot of water, that's the issue. Don't give it more water for maybe 2 days until the soil is dry and needs water. If the soil is still moist, don't give it more water until the next day.
