why the droopage?

she has moist soil, proper drainage.

temp 83F

what kind of light are you using and how close is it?

when i over nute i get droopy leaves
but in soil you could be watering too much make sure the top layer is dry before you water again. watering too much compacts the soil and crushes roots
plus you drowing it

try to get temp to 75, my plants are drooping above 83 also, when i check them during lights off right before the lights come on they are stand nice and high until temps raise above 80

just my 1st guess
