Question Squash and cucumber plant leaves turning yellow/white

Hello, I live in SW Michigan. My squash and cucumber plants have developed some type of problem. The leaves are turning yellow/white and dying. Not sure if it's the same problem for each plant or not. I'm including pictures of zucchini, acorn squash, cucumber, and sweet potato.

Hoping somebody can help me figure out what's going on with my plants!

Needs fertizer on the cucumbers..And may as well do the whol garden... I do mine every 2 weeks or so...

Use a fish emulsion

For the zucchini look for these beetles and larvae and treat with worm and caterpillar stuff or BT...Mix with the fish emulsion. And also get some 3 in one for funguse and mites...

I mix it all together in a hose end sprayer...

Assuming that nothing has been sprayed on the leaves of these plants, I would suggest that it could be a type of virus. Viruses are not really preventable, it can either be in the plant originally (or in the seed) or can be transmitted by insects or environment. Pseudomonas Bacterial Spot is another disease that looks like some of the spots on some of the plants in your photo.

Some photos look like there may be a powdery mildew problem, which can be controlled with a fungicide.

Google images may help you narrow down which plant diseases look most like the problems that yours are having.
