Plant leaves going white

Good morning happy gardeners.....well sort of.
I notice that many of you have written that your plant leaves are going pale, then white, then look burnt etc. after putting them out on a sunny day to start the hardening off process.
I have had the same problem starting with tomato plants that I put out around the end of March/early April on a fine spring day. There was a coldish breeze so I put them back into the unheated plastic house. They looked terrible over the next week and almost died. I put them back into the conservatory and they came back to life and are now planted out in the garden - although some are in a very sorry state. The same process with my green peppers. (all were hardened off)
Earlier in the week (the weather is still cool here in S. of France, but sunny most days) I put out 3 kiwano plants that were doing well in the unheated, now doors open, plastic house. Back inside early evening - but the leaves also have gone pale and today they are definitely going white. The middle leaves are ok. They stay in the plastic house.
Our daytime temperatures are between 18° and 21°C but breezy.
In all my growing days, I have never seen leaves paling or going white. The plants themselves are not actually dying but recuperating with some TLC. It's not just here, it's you in the UK, and also a Canadian is having the same problem. A plant that gets cold usually sags and get brown.
Is there something in the air that is creating this phenomena or is it just a sign of the times?
As aforementioned - they do recuperate with the warm TLC.

A good hoeing is worth two waterings.

The leaves have got sunburn

Just strange happenings. I see what you mean about the sun being at its strongest now - still, we have to get to the 21st June for the max and to the end of July until it starts to dwindle. Not being a scientist, but it's not rocket science - or is it?
Gardening in Central Norfolk on improved gritty moraine over chalk ... free-draining.
So @Pete.8 What's your prediction for this summer. A sizzler or mild as was had in the southern hemisphere. Do they follow us, or do we follow them?
So I'll leave predictions to the soothsayers
I hope for warm sunny days and frequent rain (but only overnight) - I'll try crossing my fingers and hope that does the trick 😁
