I’ve propagated this turtle vine and am seeing one brown spot on each leaf, and a few leaves on the other propagation also have one. It only gets a few hours of direct sun so I doubt it’s getting scorched. Could it be a fungus or something?
A better picture would be helpful.

Thanks for the better picture. Sorry to say I really don't know what that is. It almost looks like a tiny damage to the leaf that then left it open to some type of bacteria. That's purely a guess though.
