That would be a great experiment, but I know how you feel about losing plants. Just grow more! I grow under cheap-as-can-be fluorescent and thankfully got some shade cloth this year to protect them as they hardened off. All they really had to adjust to was temperature.
Wait until they dry out more, then repot. The goal being to get as much of the current soil out of the roots as possible without damaging them. I am sure most will pull through if you can get them into soil that drains in no more than 7-8 days. Add that perlite!
Looks like UV-B causes plants to start producing sunscreen. Those same UV-B rays get filtered by glass, shade cloth, etc. I am guessing.

I have been really turned on to scotch bonnets this year. Definitely adding some variety for next time around. The user chocolatescotchbonnet was gracious enough to send me some seeds of his namesake which I have going now. Really looking forward to following your grow.
The lemon drop I have going are huge bushy things each year. Always the first to germinate too. Consistently 3-5 days no matter the germination method!
You've got mites bad, friend. Neem will not touch them. Consider something more heavy duty, or isolate and destroy those plants. If they are spider mites, they are more easily treated than broad mites, so identification is important.
I have found the shade cloth I bought this year has worked absolute wonders for the hardening off process. Start it in position to give them 2 hours of direct sun, then two days later 4 hours and so on. Now the shade cloth mainly covers my tomatoes and young seedlings.
Check in the evening when the sun has gone down for caterpillars. That's how I found the one chewing on my orange bell last week. Damage looked similar to yours. What variety is the one with leaf curl? I have noticed some super hots just sort of do that on their own from time to time.
I got 7.8 cu. ft of compressed Promix and Klasmann Base Mix 2. Two 40lb bags of mushroom compost and one 20lb bag of Black Hen holds too much water. Either add more perlite or cut back on compost.
Have you sprayed with neem or other oils on the leaves? The first photo looks very similar to when my apartment complex accidentally power washed everyone's plants including my young peppers. They eventually grew out of it.
