Scorching, too cold or damping off??

Can anyone identify why my courgettes and tomatoes have took a turn for the worse? Are they worth salvaging or should I start again? The courgettes were fine till I put them in the blowaway while the weather was nice! I brought them back in overnight. They have been a little crowded on the windowsill.

As they are courgettes and toms I would set another round of seed, as a back up. Plenty of time yet

Did they dry out while they were in the sun? They should recover.
Oops, only looked at the middle pic. Yes. I'd start some more off.

They didn't seem too dry and it's only the odd set of leaves that have wilted like that, other ones look nice and healthy. I'll start more off anyway, think I was a bit eager this year and ended up with too many seedlings to take care of!

Looks like hot, humid conditions created in the blowaway has cooked the leaves.

How big is the tomato plant & is this just on the bottom leaves? I wonder if the plant has enough good leaves just remove those ones?

[MarkPelican]

I agree with Mr Bones. Looks like they've been cooked.
