Other than looking a bit anemic and that could be the photo color, and a couple of bug bite holes I'm not seeing any problem. No plant ever has all perfect leaves so can you be more specific?

Dave.

Three days ago the ones in the bottom pic looked like the ones on the top.

You mean somewhat droopy? Like it's especially hot or they need more water or there is a stem injury somewhere? From the photos I don't see anything else other than the anemic color.

A photo only provides limited info. Why not just state what you are concerned about specifically rather than asking us to guess?

I don't really know, that's the thing.

Depends on the variety sometimes. Red Kuri squash wilts and looks like it's a goner in the heat, but at night and the next morning, always perks backs up and looks great. Then the heat of the day comes and you'd swear it will die...Some squashes are just like that. I haven't grown the varieties that you mentioned...but watch for them in the mornings..if they are perky again, then it's just how they grow...if they continue to wilt, then it may be something else.
