Yellow leaves are hard to diagnose for sure. Observing the whole plant and knowledge of nutrition history helps. Usually yellow with clawing is the first signs of nute burn. There are other usual suspects. If I was just guessing I would probably add some calmag if I suspected I was deficient. I'm learning a lot from the spoon feed approach. Here's a short 5 min youtube which might get you started.

It could be Potassium or maybe Magnesium deficiencies. Where are the troubled leaves, on the bottom, middle, or top of the plant?

This might help ya, https://www.autoflower.org/threads/...panded-to-include-other-issues-as-well.43164/
And we have that infirmary section for sick plants too, if it gets bad.
