Those marks are not caused by leaf miners, George.
Leaf miners are the larvae of certain flies & beetles that, after their eggs hatch, they burrow through the leaf epidermis and into the center of the leaf to feed and grow. Leaf miners leave behind what looks like squiggly lines in the affected leaves. They only affect the leaves of plants.
These marks resemble damage I’ve seen from leaf hoppers, which are totally different insects.
The marks on your leaves look like something was splashed on them more than an attack by an insect. The two lines of brown on the two bottom leaves appear to be more pattern like than something random. Again, this is simply my observation.
