The light spots are most likely pests. The mangle part of the leaf you’re holding looks like either wind burn or it was a little cramped when it was forming. Nothing to worry about. Rust spots are usually cal/mag deficiency. But your leafs have a slight upturn at the serrated edges which could be heat. This could also cause the rust spots from the plant trying to photosynthesize faster than it is taking up nutrients. Every outdoor plant this year for me has done it. +95°f for a month and a half with several 100+ days. Very little clouds, no rain. Extreme heat and sun can cause some issues that look like deficiency or toxicity.
