What is this yellow affecting baby squash leaves?

Hi all,

I live in the USA, in the Pacific NW, zone 8b.

My squash seedlings were healthy until the hot days this week and I wondered what I did wrong by them.

Please look at photos and give me tips how to save them.

Top image looks like a nutrient deficiency. Bottom a fungus or disease. Mg or Fe deficiency? Is watering correct?
Either way I’d shade them from the late sun if you think the sun is too strong. Sorry I don’t know your zone. Don’t water the leaves and make sure the soil is tip top.
