Spider mite look alike.
According to Missouri botanical garden. Org
This is spider mites on tomato leaves
According to Sow the Seed UK
This one is a potassium or magnesium deficiency or imbalance
More spider mite damage ; leaf undersides
Gardening with Allen: What’s up with discolored leaves?
I think I have also seen aphid damage and thrip damage look alike.
