White mildew issue

Gibson's Grow 905 said:

Hi I have the start of white powdery mildew I think. Anyway I have the black saucers and elevators for my fabric pots. After watering plants I left the run off in the pots so its a white residue.. can I spray it with peroxide and kill it or tea tree oil or mix them with water? I was just gonna pour a bit of one or the other in to the saucers.
Also is leaving the run off in the saucer pots a bad thing.. I just figured it would evaporate. Anyway if anyone can help thanks.
A friend said use 60ml peroxide with 60 ml of milk and mix with 1 gallon of water or 5 liters to spray everything down. Is this correct information and good for the plants ?
Also.. I got/ waiting for a dehumidifier and a air purifier to help fix the issue. Will it help any ideas thought would be appreciated. Thanks!

I do yes, Apartment city water. You thinking what you see on the black saucer pot is just calcium build up from.letting it sit and evaporate?

Okay thanks. I didn't even think of that.
Can it eventually grow on the leaves here and there or ?

Molds and fungus have to have a host food source. Black plastic is not a host.
