I need help diagnosing this issue

I have this auto that has started to show signs of what i think looks like something calmag would take care of but i would like the more experienced set of eye to give me their opinions! Any ideas why this girl is turning yellow ?

I would try up potting it into some fresh soil and a bigger pot. In my opinion less nutes is more on autos. It’s only a few lower leaves, so not critical.

They may start to flower if too root bound. Or worse over blasting it w cal mag could cause it to burn, nute lock, or also go flower time. Veg is over.

Fresh soil under the old pot soil and more space is what I would try first.

looks like mag over calcium. I would try some epsom top dressed in first. Non invasive. Takes a week to see it work but the small calcium spots dont always mean low calcium. Calcium and mag work hand in hand. Low on 1 tends to affect uptake of the other. I see mag symptoms over calcium from here. Just me.
