Did you switch to so-called "bloom nutrients?" Sometimes those are too high in PK (not enough N). Sometimes people "switch" too soon, too abruptly (when they could mix "veg" and "bloom" to get something in between).

Could be salt buildup. That's common in early to mid flower. It's worse than yellowing. It will look blotchy, crispy leaves.
