mold is easily killed with some hydrogen peroxide 30mL or 2 tablespoons to a gallon of water. you could even use up to 3-4 tablespoons of the 3% stuff.

the 35% food grade is reccomended usage at 2 tablespoons per gallon.

It will kill the mold and not your plants. just mix it up and water as usual.
