What’s with these leaves

Hello aga growmies,
I’m week 5 or 6 of flower and one of my plants have theses bronze areas. Is it rust spots? It doesn’t really rub off on fingers or smudge. It’s not on a lot of leaves….yet. I’ve looked at several charts but can’t pinpoint what it is. Any help would be appreciated. Thanks in advance

Some more information would be helpful, medium, ph, feeding schedule/ec.

it seems to resemble a boron issue but I would like to hear more about your grow before you go chasing non-issues.
