Yellow blotchy leaves

I've been growing since Nov. And I started 12/12 close to 4 weeks ago. I beleive I have an auto flower because it started to bud before I switched to 12/12. I began giving them cal.mag
And they perked up and did fine. Then I gave them a bloom booster and since then only one of my plants started to get a yellowing that is blotchy, my buds look really nice but I'm worried something is wrong and would like some advice. Any ideas?

Looks like a calcium issue, what was the booster used?

Sensi bloom part A and B And cal mag 2.0.0 is what I started with. I'm new at this, my grows are usually 1 plant but im doing two right now, the other one is fine

I'm guessing I have another 4 weeks before they are done.

I have done the same thing with both of my plants, the smaller of the two I beleive is an auto flower( the one that's blotchy) my other one is perfect.

Calcium issue. The question is it lockout or deficiency.
