I don't think it relates to spiders mites since I can't see any with my 30x magnifier. Thank you so much in advance.Leaves. Color - Yellow

Defficiency or light burn?I Had this on my previous plants, I'm starting to think it is light related as it seems to happen to the leaves closest to my mars hydro. I wonder what would be the best course of action here?
Ive added a tiny dose of calmag, can I supercrop this late into flower?5y ago
