Just a guess. Looks like bacterial spots.

Looks similar but I can't find anything that says bacterial spot is a
potato problem. Everything I've found says it's a tomato and pepper
problem. Maybe I've discovered a mutant variety...hmmmm. So far, it
doesn't seem to be affecting the plant. Some leaves are yellowing at the
bottom, but I expect that this close to August. I did find something
that said pollution can cause a peppered look on the leaves and doesn't
really affect the plant. Perhaps that's it.

While I'm on the topic of yellowing leaves....any reason why older corn
leaves would yellow? The five I have planted outside have yellowed a
little and the plants are shorter and lighter green than the ones in the
greenhouse. Is there a concern there or is it just a result of being
outside?

Thx!

Corn loves N. Use more N.
