Squash leaves turning yellow on edges, then brown and dry

I'm growing an Everglades Pumpkin Squash this year, for the first time. It gets plenty of sun and water, and the fruit (once I learned that I needed to do manual pollination) seems to be just fine. But the older leaves on the plants, around the two mounds I have built up, keep dying away.

First they completely turn a lighter shade of green, then a bit of yellowing appears along the edges. After a couple weeks, this begins to turn into a dry, brown dead leaf until the entire leaf dies and I just pluck it off. I see no "saw dust" or other signs of bugs.

What could be causing this? One of my neighbors recommended adding epsom salt to the soil next time I water.

Thanks!

Is it only the old leaves, or is it affecting all the leaves?

It's common on squash that older leaves die off as the plant grows. As long as the newer growth is fine and it's producing I wouldn't worry about it.

Summer_Squash, it appears to only be the old leaves. The further down the vine I go, the better the leaves look.

I just checked. Some of the decaying leaves do also have yellow spots on them. And I found two very small but already dead/yellow fruits.

Small dead fruit could simply mean they weren't pollinated. Your plant sounds normal, though it would be easier to be sure if you could post a photo.

Thanks for your help! By small dead fruit, I mean about pea sized - well before the flower opens up for pollination. If I don't just pluck it early, it turns brown and dies without ever flowering. This hasn't happened much (3-4 times).

Photos posted.

Here's an overall view (so you can see that it's limited to a relatively small area)
