What’s happening to my grape vine leaves?

Maryland fruit pest insects and mites

Hi- the white squiggly lines are probably made by serpentine leafminers (small larvae feed between leaf surfaces). It's a minor pest in this case and no treatment is necessary.

No need to be concerned about older leaves yellowing or newer leaves being small and off-color this time of year.
