White fuzzy cover on all dirt of plants and trouble with growth

I have had my garden for about 6 weeks and just love it. I have havested the lettuce and the basil a few times. Tomatos and peppers are growing but not evidence of either. Peppermint not growing much at all. All of the plants have a white fuzzy covering on the dirt. Help?

Hi! If any of your plants have not germinated in 3 weeks, please contact with customer support and they will replace faulty pods. If there is a mold on the soil surface, wipe it off with damp paper towel and add cinnamon on the top of the soil, which has natural antibacterial properties.
