I tried my best to find something that related to those pics and your info. I think taking the steps you're taking should be fine. As far as "bacterial" goes, I threw that out there because it didn't look like bugs. You're probably looking at 3-4 weeks to harvest, (if I read right), so just keep...
imo, it looks bacterial. the first couple pics looked like they were being eaten, but the close ups,( which are really nice btw), look a lot mor uniform. wish I could help more. good luck.
