Spots on tomato leaves?

[Maggiethecat]

These spots have appeared overnight and wonder what’s caused them?

this other tomato plant has holes - they’re both in a small cold frame

Looks like pest damage.

Just need to work out which pest and how to treat!

Not necessarily any need to treat. That isn’t reducing the functional leaf surface enough to need treating.

I’m not convinced it’s pest damage.

It’s curious - I was wondering if the spots in the first photo are due to something dripping on them.

I gave a soap spray just in case!
