Unknown problem

What the hell is this orange/yellow stuff growing in my soil? I'm using fox farm ocean forest and everyone of my plants started to do this? Looks like a start of a mushroom or something? Is there anyway I can kill it or save my plants? The plants themselves seem to be doing fine but I have always done dwc hydro and tried to do soil this time. The soil was purchased last year.

It does look like a mushroom. Have you been seeding spores? For them to exist they need a moist, humid environment, which is the opposite of what you need for your plant. Get some air movement going, and let the soil dry out before watering and that should kill them off. Peace
