I was about to post similar pictures. My tomatoes have the same condition.
I believe it's edema. But i could be wrong.

That looks like a combination of edema and mites (or thrips, or scale, or whiteflies, or some tiny sucking creature). I personally wouldn't worry too much, but I'd encourage ventilation. You probably won't see any more of it after the transplant, I'm guessing.

Most certainly edema. Be careful, it can be fatal on susceptible varieties. Once the stem is attacked you can forget about it. Brad's Atomic grape died on me, it was the only one affected, that's how much the variety matters. The petioles started curling badly with bumps on the underside, and then it slowly died. I would get the affected ones outside during the day for some UV and air.

Edema, indeed it is.
In my experience the affected pepper leaves won't survive - they aren't diseased though, so you can keep them for the bit of functioning green until they get new ones or are obviously dying back. They may last longer than you expect, ie they tolerate the edema and keep working for a time, in spite of it.
Also pepper stems being woody, they are less susceptible to a fatal bout of edema, cw tomatoes. With tomatoes, it really threatens to be fatal when it affects the stem vasculature. I've seen peppers tolerate a fair bit of it on the leaves, and go on to do just fine once you plant them out.
All good advice though, to get them outside as soon as you can, or at least just put them on a windowledge where they can get natural light. I have grown peppers in windows here without supplementary lights, and they are really fine with the amount of natural light from south or west (our east side is a bit too shaded) even in the cloudy climate that we have. So moving to a window is a perfectly good bet, if it's still too early to be taking them outdoors.
