Could be mag and P def but they look generally underfed. You might try feeding at 6.6 ph next time to help mag and p uptake. Also the first 3 weeks or so of flower they use a lot of nutes stretching and gearing up to flower.

Or she could just be cannibalizing older less useful leaves preparing herself for flower. Especially the fuller bushier ones

Definitely underfed, your soil is used up and need to start feeding more regularlu

I agree with the phosphorus deficiency and overall under-feeding. Plants starting to flower start requiring increased amounts of that P and K.
