calcium and magnesium are 2 different things. you can have a deficiency of one and not the other. looks like hint of interveinal chlorisis. More than one cause of this symptom, unfortunately. If you start getting rust/brown spots with it, then you can consider Mg deficiency. However, calcium deficiency does not have interveinal chlorosis as a symptom. it's just rusty / red spots. That spot in picture 3 -- it's so irregularly shaped it makes me think it was touching something or bent .. just oddly shaped to be caused by nutrients given. The other mark is parallel to it on other side of leaf slightly shielded by another leaf in picture. that's weird if it happened naturally from within the plant due to nutrients. now, lockout of any nutrient that causes interveinal chlorosis is a possibility too. it helps to understand how much of each nutrient you feed and keep a log of it over time. othwerise, it's more of a guess than necessary. pH can cause symptoms to show even when there isn't a lack of supply, too. When it isn't a dumpster fire, these things are often caused by weeks if not more thana month of previous behaviour. The longer it takes, the closer you are to finding the best balance. Double check pH. Consider recent fertilization and any changes made over time. I'd give this a couple more days to present the symptoms more clearly. i don't think it's lockout or ph-related because those issues tend come with coinciding symmptoms of more than 1 problem. This seems slow moving and should be straight forward.
