I probably do need another light, seems most people use 3 and I only have 2. I don't think that would cause the issue though, probably just less growth.
Seeing some fuz, but nothing that jumps out to me as more than root hairs. But maybe I don't know what I'm looking at. Trimmed it out to try and get a better look.
This is the full rack. The bad side was up to the wall, but I don't know if that matters. 
Just recently starting growing microgreens. I had 2 trays that turned out excellent. My last tray and now this current one are doing as shown.
I wouldn't be ok with that. But I also think the path to legal immigration needs fixing. And that for example farm workers should have a legal way into the country for work, while also being provided the same worker protections every citizen gets.
Hmmm. We do have a new kitten that likes to mess with the bottom shelf so we try to keep the door shut most of the time. I'd think I'd probably notice the other trays having damage if it did jump up there, but it does look like a pretty nice spot to nap.
