Brown Patches on Older Leaves Slight yellowing and brown mottled patches. Only on one of the two plants and they’ve been treated and fed exactly the same. On some older fan leaves, no signs of anything on new growth. Anything to worry about at this stage? Maybe just a sensitive pheno? Any advice appreciated.

Calcium deficiency I already had a question a week ago, now it's easier to see, camera still bad. But here are some fan leaves which I believe are showing a calcium deficiency. Calmag is in the post, just waiting for it. Is it for sure a calcium deficiency only? Thoughts?
