Is this a calcium deficiency?

I’m thinking this is a calcium deficiency but wanted confirmation.

It looks somewhat like a Ca deficiency, but the color isn't what I'd expect to see. When I see necrosis like that on the upper curve of the leaves, I think light burning. How close is your light?

Its a good two feet but its high wattage. Maybe I need to switch to one of my smaller lights? It was just on one branch but it seems to start showing on others in the last day. I upped my calmag yesterday. Its more spotty on the other leaves than concentrated like this.

Calcium is immobile. It's symptoms show at the top.
