Tiny brown spots with yellow halo

[Suzanne17]

This is my new Monn. Millennium Magic 'Witchcraft'- I didn't even notice these spots until today when the leaves were backlit. They do not rub off and nothing on a paper towel when I wet it and rubbed it on the leaves. It's on every leaf. I'm guessing fungal though when I googled I didn't see these type of tiny spots and so uniform. For scale there is a stake right behind the leaf.
