You may want to let the soil dry out and or use as very dilute solution of water and hydrogen peroxide. The ladies don't look that bad.

hi eastbaygordo / LetsSeeYa i will give it a go let them dry out abit first thanks for all your help you both are stars regards toe

Hold your horses.

That looks like coco. If it is, don't let it dry out, ever. Coco is actually a hydroponic medium. Your plants, which look good, may not recover if the roots dry.

Fill out the form in my sig and people will be able to give more detailed advice. Knowing what you're growing in is important to know.

The mold/fungus on the medium's surface is most likely a beneficial that's breaking down your nutrients so the plant can use them. Peroxide will probably kill it. Do you want to do that?
