Cucumber Molybdenum Issue?

[DirtMechanic]

When I set up the garden for my wife I tilled in Black Kow composted manure and that was all. We discovered later that it had something like Grazon in the compost, so its a weird garden this year. These cucumbers were looking good, but then they fell apart. I have seen manure compost run out of nutrients with grass, and I am suspecting something along those lines. Thing is, with the herbicide issue, I am in above my pay grade. Look at these pics please, and give me your thoughts?

This is a pic of a molybdenum problem of cucurbits from the Texas A&M website. Its about as close as I could find for our plants.

I am pretty sure I may have scorched them with a spray, but why I am puzzling is the trellised cucumbers behind them that are not showing the same effects. Well there is a handfull of leaves shown here:

Are the cucumber fruits normal? Are all of the cucumbers the same variety? When the problem first started did the plants look like a plant with iron chlorosis? Are any of the other cucurbits affected or just the cucumbers? Were the squash planted later than the cucumbers? Do you have any melons planted and if so do they show any of these symptoms?
