[Wait...What?]

I would have said aphids, but either way, turn the leaf over. Critters are likely feeding on the leaf from the underside.

most likely genetic. if it was pests it would be on all the plants not just one.

What about the tiny black speckling on the right & upper-right? That looks like either fungal and/or bacterial spores... you using any beneficials?
