Is this a problem? Gosh I hope not..

Using smart pots, so water drips from the sides. 2 pots are right next to each other and both have this on them. Is it something to worry about? Thanks!

Also, from time to time I tend to see little flies or mosquitoes flying around, but I kill them quickly. Is that bad?

Hard to say in that light but that looks awfully like fungus of some sort

Fungus.
Flies.
Fungus Gnats?
Dont let those pots touch either man. Besides growing mold /fungus. The roots think its soil. Because its dark. Then they push through, the pot.

They're in a 4x2 grow tent, each pot is 1x1, 8 pots

I will take better pictures in the morning

Can see what looks like roots poking through lower down on the pic, but the main white patch certainly looks more like mold
