Brown bottom fan leaves

was it recently watered before that pic? if so, that would explain the droop a bit. I think this is a P-deficiency becuase of the blueish / dark leaves. Possibly N too. You should feed a well-balanced dose of nutes.

Hello Will the yellow/brown leaves pull off easily? Or any falling off on their own? Usually that dead bottom leaves are associated with nitrogen deficiency and if you haven't been feeding nutrients then that's most likely the problem. Fortunately being in flower they need less nitrogen anyways. As for adding nutrients you could bring in low doses of a bloom nutrient. Happy flowering.
