Not sure whats happening...

I am wondering if anyone has any ideas...Top fan leaves are drooping at the tips, and some are turning yellow. If I look on some of the smaller leaves inside the plant, they are drooping and sagging as well. Too much water? not enough nitrogen? shes about 3.5 weeks into flowering.

During veg, marijuana plants store nutrients in their fan leaves to be used during flowering.
As these nutients are used up, the leaves brown, wither and die.
It's natural; it's supposed to happen.
