Leaves Curling... Heat stress or over watering???

Hey guys i have a girl in a 2L soda bottle, she is about 2 weeks into flowering and 5weeks old, the temps are around 80 degrees and the humidity is around 40%. since the first feeding with nutes about a week ago she drinks all of her water in a few hrs, so i end up having to water her every day. Is the curling from watering her almost every day or the low humidity?
Thanks in advance growers.

Pics? If the soda bottle is clear that's the problem light to roots is bad it kills them

Just the bottom is clear and the roots are fine, nice and white, i have grown all the way to harvest in a 2L soda bottle.
