Microgreen Issues
(piefedimages.s3.eu-central-003.backblazeb2.com)
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. 
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.
