Looks more like pest damage. Maybe thrips. Check bottom side of leaf for small bugs, sometimes you need magnifying glass to see them.

Brown yellow leaves?Can anyone help me? I had this issue with my last early Miss and thought it was a cal mag deficiency. I tried to adjust it last time during flower but it didn’t help. I really only notice it on one of them so far but I would like to fix the problem sooner than later.
