Can someone tell me why are these leaves folding up in the middle? This plant has 4 weeks of flowering, halfway through. Thanks

Cupping can be caused by excessive heat either from the overall temperature or if it is mostly the leaves on top it can be from the lights. Also, a root problem can cause the leaves to curl so make sure you are pH'ing your water and not over watering.
