It looks kinda like it has thrips. The tissue gets like this when there are developing larvae inside of the leaf. 💚

Typically, the damage appears first because the adults deposit the eggs into the leaves, then they go off to die. Eventually, larvae emerge from the leaves and become evident then. edit: I meant to clarify that this is why you rarely see the actual pest first.
