Strawberry Leaves looking grim

[Marb67]

Yet another hit for my plants by another mystery. This time my strawberry plants are getting some kind of leaf miner in the leaves as well as the bubbling, twisting and distorted leaves I get with a lot of my plants. No pest on them to identify what it is. Some plants are older and some were bought this season and were healthy.

You do wonder why you do this sometimes.
