I've gotten help both times I posted a thread, and I think I owe this mostly in part to 1) being patient (expecting a quick answer within half an hour is a bit unrealistic) and 2) providing as much information as possible.
Don't worry about not getting a quick answer in the first hour, because plants are slow growers and a few hours isn't going to cause any significant damage, and usually by then someone has responded.
For example, what color is the mold? Are you sure it's not just algae? I hear that is quite normal, but maybe yours is white or..?
Do you have a camera that you can snap a picture of this with? I'm not the best with growing myself, but maybe seeing it might remind me of something I've come across.
Peace!
