Droopy leaves on my biggest plant

Hi There

Im wondering why my biggest plant is got droopy leaves . It was 32Celcius today and the earth was dry The leaves where already droopy .

I water at PH6.5 and the plant still look the same .

1st week of flowering
11 tops Cant wait to see her in late flower🤩

32c is hot. Mine can get a little droopy when temps get that high, I’m guessing it’ll perk up once temps get down. When was the last time you watered, what size pot, how much do you water?
