Indoor seedlings- after 2 weeks

I'm starting to get worried about fungal problems again. Nothing has died yet but the soil is turning slightly green in some containers. Maybe I'm watering too much? I'll be taking them outside for fresh air as soon as this snow we got today melts. Google said that sprinkling cinnamon might help with that so I did that.

Peppers are finally coming up which is actually a surprise. I thought the air was too cool in my house for them to germinate but maybe sleeping by the fire helped :)
