Spots on herbs
Hi Jean - This looks like leafhopper damage on the herbs. They are a sucking insect. Typically they are gone by the time you notice the damage. Parasitoids and general predators (ants, spiders, ladybugs, lacewings) help to reduce their numbers. Keep weeds down especially perennial weeds that may harbor their eggs.
No chemical controls are recommended for this. It is okay to eat the herbs that do not have a lot of damage. Remove the badly damaged leaves and the plants should put out new growth. Here is general information about leafhoppers. https://extension.umd.edu/hgic/topics/potato-leafhopper-vegetables
