Is this typically cal/mag deficiency?

If I'm not mistaken the little Brown spots on the lower fan leaves indicates that this is a calcium magnesium deficiency. But I water with 6.5 ph tap water and even added a 1/4 strength Cal/mag last watering. Spots were there before the cal/mag feeding, I thought that would of fix it but it didn't.
And my four other plants on the exact same feeding cycle are showing no signs of any sorts of deficiency.

Looks like bug or splatter damage. It's not a cal/mag issue. Monitor it, don't start throwing stuff at her.

Hey did you find out what this was as looks exactly how mine look Im thinking splatter damage on mine hopefully not bugs

ph fluctuations

Have a look at the underside of the leaves.
calcium deficiency will show a dent in the leaf on the opposite side of the brown dots.

and once you have calcium damage to you leaves, it is permenant. It’s now the parts of the plant that haven’t got the brown dots you want to keep an eye on.
