What is wrong with these squash seedlings.

they are spotted yellow. On the ones with new growth it does not seem as bad.

Here is a more affected one

I often get that look when setting out squash or cucumbers and think of it as sun or wind damage. The ones sown in the garden don't do that. Maybe it's transplant shock. The new growth straightens out just as yours did.

Hmmmm, I planted them in the garden. There were a couple that perished but most of them seem to be growing now. I have never grown squash but I understand vine borers and squash bugs can cause quite an infestation. I thought maybe I had bugs of some sort.

Could it possibly be from the fluctuation in temps? We've had such weird weather lately.
