My squash leaves started turning yellow. Some leaves underneath look dead. The yellow leaves are limp and not as sturdy as the green leaves. What could this be?
Lack of water can cause yellow leaves. Squash plants need 2 inches of water a week. I would check for pests also. This article should help:

In the last 2 days I’ve begun noticing browning on the leaves of both my tomato plants and some of my squash plants. I live in Utah and we had a large fluctuation in temperature a few days ago. I have been careful not to overwater. It has been hot the last few days. Any help would be greatly appreciated.
That is a fungus known at Phytopthora. This article will help:

watered daily we live in the Yucatan it's hot and plants get 6-8 hours of sun most days
This could be due to several reasons. The first things to do will be do test the soil for pH imbalances and deficiencies. These articles will help:

Likely, there is not enough phosphorus, potassium, and calcium/magnesium in the soil. A soil test will confirm.

Too much peat moss? Can I move them now? I know the roots don’t like to be disturbed. The two in different soil and location are very healthy with squash forming now. Should I try to “dig in” some soil amendments or use a liquid fertilizer? Which one? Thank you!
I wouldn't move the yellow ones if there are signs of fruit. This article should help:

This is my first year planting squash in containers. They started out big, green and beautiful and a few of them started to produce really nice big squash and zucchini. Then all of the sudden they started looking stressed. Production has slowed to a crawl and the ones that are setting fruit are not growing big and bountiful. I’ve tested the soil and Nitrogen, Potassium and Phosphorus all are ok. I’ve added Salt for magnesium but nothing seems to be improving. No bugs or pests of any kind I’m pretty sure it’s not mildew. I’m wondering how about iron deficiency but it’s really stumping me. Any suggestions?
Unfortunately, the photos don't show the soil. It could be an infection in the soil from remaining too wet without time to dry out, thoroughly, down to about 3 inches or so.
But, even more likely, it looks like a spider mite infestation has caused disease!

I keep reading that they only get 2 feet!! But mine are definitely at least 6 feet. They also say they produce high yields early. I have 4 squash, and 2 of them just came to fruition. The fruit is definitely a sugaretti squash though. I'm not sure why my plant is SO big with so little amount of fruits. Please help me.
This sounds like a case of too much nitrogen in the soil. This will cause larger than normal plant stature, while eliminating the ability to fruit, properly, if at all.

This is dinner plate sized and heavy. What is it called? Is it edible? If so, how do I prepare and cook it? Thank you so much for your help.
