I asked a question the other day about the leaves on my squash and cucumber plants, but the answer I got was that I had blossom rot - which was WRONG. The vegetables are fine, and the blossoms are falling off the way they should. My question was about the discoloration of the LEAVES. Will the yellowing of the leaves affect the fruits and vegetables? I've been growing veggies for awhile, and this has never been a problem for me.
We apologize for the confusion.
We are answering lots of garden questions this time of year.
Yellowing leaves usually indicate a watering issue. Either to much or to little.
If the soil is dry you may need to water even twice a day, especially if the summer temperatures are above 85 degrees.
There could be other reasons including insects or fungus.

Downy mildew on squash plants.
ok thank you
Why are squash plant leaves turning yellow?
If you've gotten a lot of rain lately, this could be the problem, simply too much water. This article will also help: https://www.gardeningknowhow.com/edible/vegetables/squash/why-squash-leaves-turn-yellow.htm
I have a yellow and acorn squash plant growing in my garden. When the vegetable starts to grow, within a couple of days they shrivel up. I'm not sure what I am doing wrong. Thanks for you help.
It sounds like you are having pollination issues. When the flowers are not properly pollinated, the plant will reject the fruit while they are just a few inches long. You may need to hand pollinate. This article will help:

Why are the blooms falling off and not putting squash on?
This is typical behavior for a squash plant. They will produce mostly male (non-fruiting) blossoms early in the season and will gradually start to produce more female blossoms as the season progresses. The male blossoms typically drop from the plant and seemingly disappear. Give it some time and you will see it start fruiting.

Can I treat fusarium wilt on my squash plants, or should I just remove the leaves? The fruits are fine, for now.
Most likely the plants cannot be saved.

My squash plants seems to be suffering from squash wilt. Is there any way I can save the plants? The squash, cucumbers, and tomatoes on the vine seem to be growing beautifully, and I would hate to lose my harvest. Is it possible that something else might be turning my squash leaves yellow? We have been getting a ridiculous amount of rain for the season. Also, with the amount of rain we've been getting, I'm wary of using any more water soluble fertilizer in my garden for fear of over watering. Do you think 10 x 10 fertilizer would be too strong to use?
Your yellowing leaves could simply be the excess amount of rain you mention.
Plants that sit in soggy soil can die from root rot.
These stressed plants then in turn will be more vulnerable to insects and disease.
I would not try to fertilize them into health. Do not fertilize.
You could try Epsom Salt. I use this during the hot growing days of summer with quite good results.
I'm including some links for you.
