I'm worried it might be mold. It's only on the plugs. I've had it going about a month. Water changes weekly, except at the beginning when I didn't realize it need water changes. Then it went almost 3 weeks without a water change.
Is there anything I can do to fix it if it is mold? When I googled, all I could find what that is was a beneficial white fuzz.
System is an aerogarden knockoff from Amazon. (Lettuce is doing great and has already been harvested once, these are herbs and they're a little slower but growing steadily.)
