Tried to find similar pics on the forum but cant see anything that fits..

im guessinf it could be using too much nutrients(was a bit careless when measuring out the chilli feed maybe), overwatering or pests.. or maybe a combo of all 3. Used bug clear ultra so 4th option could be a bad reaction against pesticides..

All looked fantastic until I took em outside for the first piece of sun but all above mentioned bits may have affected them. Super grateful for any advise.

Yeah? So not pests or pesticide issue? Nor too much nutrients? Is there a remedy? Weather hotting up here in the UK so was hoping to boost them outside.. currently just been inside under the lights for a few months..

No i'm like 99.9% sure it's sunburn. When you have them indoors under lights, they're not used to the intense rays of the sun so you need to "harden them off". introduce them to the sun slowly. Start in the shade then move them into the sun for about 15 minutes, then gradually increase their exposure to sunlight a little more every day til you can leave them out permanently. You can probably pull it off in a week depending on your weather but I like to stretch it out for about 2 weeks to lessen the shock.
 
OK very grateful for your comments. Just seem to be all the superhots(various habaneros and trinidad morugas) that got affected from the sun, these had been under lights for months. Jalapenos/Serranos/Little Elfs that had more exposure to windowsill light and less artificifal light have done better and show no signs of being poorly. Kept them out for two days straight in full sun and look very healthy.

Reading up more on it and seems you are probably right! Soo... no cure seemingly.. does one keep em under the artificial lights or give them low doses of natural lights? Heatwave here in the UK for the next few days..

Rookie mistake here seemingly and thought I had most or alot of bits covered :)

Not really a cure. Once the damage is done, the damaged leaves with likely die and fall off at some point but the newer leaves will be fine. Just transition them slowly to the outdoors. It would be like your skin never seeing the light of day then suddenly you're thrown into full sun all day long. You would burn pretty easily. You have to do it slowly. Most people (myself included) learn the hard way. I killed 15 plants about 8 years ago taking them directly from the grow room and putting them outdoors. Not a single one survived. Yours look like they'll be fine but just take it slow.
 
So grateful.. thanks.. but what do I do?
A, avoid growlights and natural light and keep indoors
B, expose them still to natural light but keep them mostly under grow lights
C, stick to grow lights only until recovered
D, skip grow lights but give them increasing levels of natural light
 
Nah just move them outside for a little bit everyday and bring them back in under the grow lights when they're done. If your work schedule or whatever makes that difficult then you can just put them in a spot that's shady all day, then move them to a spot under a tree perhaps that gets majority shade with a little filtered light, then to another spot that gets a little more light. Do a youtube search for "hardening off plants". Theres a ton of videos on different ways to do it.
 
Just what Edmick says. Be patient and give them shade for about a week with a bit of sun in between. Then slowly add full sun. Slowly.
 
I keep my plants under sunscreen fabric for a month after potting outside. They get both sun and shade until July, then I know they are ready for intense full sun.
 
Sofar not a single plant from the 6500K and 8000K bulbs i put in a south facing window show any signs of sun burn. If anything they seem to love it.
 
     They don't usually get sunburn through a window. I think they filter out a lot of the UV that causes sunburn.
 
     Do you keep that humidity dome on your plants all the time? Some of that damage looks like foliar disease to me. Bacteria thrive in humid environments where leaves stay wet because moisture can't evaporate.
 
as has been said, definitely sun scald.  Any particular reason you're putting them outside now?  Correct me if I'm wrong, but it doesn't seem like the temps in London are conductive for pepper growth yet.  You typically don't want to bother putting them outside until you're ready to leave them outside permanently.  I've been told also that moving them back and forth from inside to outside constantly could cause significant pest issues, bugs like aphids will spread and there won't be anything to control them inside.  
 
You also want to ditch that humidity dome as soon as the seeds sprout.

Always kept it on but taken it off now, realised now after ze commenta that maybe its only needed for the germination stage.. dont know if its bacterial as all new leaves are fine and doesnt seem to be spreading.. or at least not fast if so.

Ditched the humidity dome or the top at least now after the commenta, maybe only needed for germination? Left the heat on the propagator on maybe too long, should it be switched off after germination?

Moves them outside the other weekend when it was 25 plus degrees in London but most of the habaneros didnt seem to like it, Jalapenos, poblanos and serranos seemed to handle it fine.. will wait til all has recovered and use shade cloth next timw they go outside..
 
     Keep your eyes peeled in case that gross looking stuff starts to spread. If I were you, I would be picking off the leaves with the brown, water-soaked looking lesions. Bacterial leaf spot can spread really fast.
 
I don't personally see any signs of bacterial leaf spot in the pictures.. All I see is sunburned leaves. That dome is definitely a bad idea at this stage of growth but I don't see any signs of disease in the pictures though..
 
This is a close up of a Big Sun Habanero, leaves have not gone any worse in the last week but remained the same..hoping for sunburn ans not bacterial
