Did you spill concentrated liquid fertilizer on them and not wash it off?

Brian, just covering all bases, but did you look at underside of leaves for mites?

I would sacrifice a couple leaves get white paper ready cut the leaves tap the bottom side on white paper. mites are a lot easier to see on the white background.

I would guess spray damage, with the veins staying green, and only a handful of leaves affected. Aphid and mite damage would take an infestation to look like that. Might have had some overly concentrated amount on those leaves some how? See if this helps in any way: https://www.bigpumpkins.com/Attachments/Leaf_Problems_Summer_2011.pdf

Not feeding enough and/or strongly enough. ('once a week, dilute'); A plant is usually just-barely putting on a good show and once tasked with a developing pumpkin as well, begins taking from established growth to fill any void(s); I looked into what would happen to a human if starving and it was not a good scenario at and beyond 72 hours, lol. When I extended it to AGs, the description was very well-detailed and coincides with my thought; (Just the one - I don't wanna overdue it, lol);
Imagine a famous painting with sequentially-missing colors over a week or so. Somebody else needed all the reds, then blues, then...yikes! I do not feel that any solution will restore these colorful leaves, but the rest will benefit, I am sure, from what is deemed to be needed. eg

That picture looks similar, Will have to research this. It would be odd to only be a couple of leaves. Molybdenum wasn't tested on my soil test.
Will cull those leaves this afternoon and check them on the white paper to double check. I don't think it will be much of a sacrafice as I can't immagine they are helping me much at this point.

Thats interesting how it resembles that molybdenum pic. But I believe the Patons (and others) are running low (near zero) molybdenum again, with no serious adverse affect. I've seen other low molybdenum pics that do not look like that, so I am skeptical. I'd say disease, or something got spilled onto the ground at those nodes and nowhere else. Some micronutrients will really mess things up if a container spills or leaks.
