Is this cucumber mosaic virus?
I got something on one of my plants that looked like this last year as well, but there was similarly no leaf stunting. I took a chance and left the plant in, and it continued to produce normal-looking and -tasting fruit until it was taken down by bacterial wilt and powdery mildew.

And the year before that, I was growing sanditas/mouse melons, and one of my plants got some weird yellow speckling but continued to produce fine.

But I don't know of any nutritional or physiological problem that looks like this. Sure looks like CMV, but there's no leaf distortion. :? I have another plant right next to this one that shows no discoloration at all.

Anyway, I'd appreciate a more experienced eye and opinion on this.

The variety is H-19 Little Leaf. Leaves are not stunted--they're normally smaller than most cukes.

Wetness is due to the fact that it started raining just as I was snapping these photos.

Just checked my notes, and H-19 Little Leaf is supposed to have CMV resistance. Which, of course, doesn't mean it won't get it. But now I'm at a loss. Perhaps it's a different cucurbit virus?
