HELP (all my outdoor plants have revolted) whats going on?

I live in Western CO.

The plants all seemed fine over the last few days but it seems like theyve all revolted against me.

One in particular has it worse than others. The inside of the greenhouse is getting warm even with a strong fan. Is this heat stress?

This only happened to my outside plants. The indoor ones are great.

First 2 pics look like sunburn to me with the whiter areas on the leaves.
You may need a bit of shade cloth.
