Marigolds, clovers, and other plants have leaves mottled with white

Question

I noticed our marigolds all seem to have some sort of leaf-mottling, but since they seem otherwise healthy (perky, blooming), I wasn’t too worried about it. But I’m noticing the same thing has happened to nearby plants: bee balm (wild bergamot), black-eyed susans, purple clover, possibly oxalis (not sure if it’s oxalis or clover in the photo). Nearby milkweed and New Jersey tea plant seem unaffected. It doesn’t look like it’s on the leaves like powdery mildew, but like part of the leaf itself. What’s going on? How might I fix it? The affected plants still seem otherwise healthy.

This is some kind of mildew and is common in areas of high humidity. It's mostly aesthetic. I'm not sure of how to treat it. — user1469762, Aug 18 '21 at 02:00

From My Marigold Leaves Have White Spots

The red spider mites cause white spots on marigolds. They leave white weaves of webs, feed off your plants, turn the leaves yellow, and slowly kill your marigolds.

Apart from natural methods such as Removing the infected plants and destroying them, there are some methods listed at the same site

Rosemary Oil

Insecticidal soap

Neem Oil

I was told this is from red mites and needs a miticide.
