Oh no! Something very wrong with squash, bean, and ground cherry leaves in west bed! (maybe sunflower too)

First noticed it maybe ~2 weeks ago, on the northmost vertical squash in the west bed.  Didn't do anything about it.  Now whoa, those leaves are quite yellow, and speckled all over with something, top and bottom.  I don't see mites or aphids or anything like that.

And, what looks like the same thing is also expanding in the west bed beans, the west bed ground cherry, and possibly the west bed sunflower.  All those things are all close together.  The beans have it the worst, along with the squash.

Additionally ------ now the central ground cherries are also starting to show signs!!!!!!  Just starting, though.

So, today I pruned a bunch of leaves off that one vertical squash, placed in yard waste bag immediately.

Took photos of the leaves, will post to Edible Gardens tomorrow in the hopes of a diagnosis as my internet search wasn't successful.
