Fertilizer Encourages Fungus Growth

I bought ohrstrom's garden maxicrop, original liquified seaweed from you. My plants love it, but it makes these orange things start to form and grow on the soil, that look like mold. Is it mold? It even grows on the plants. I think it is sort of bad. What exactly is happening? Am I using too much in the solution?

It certainly sounds like some sort of mould. It does not seem to harm your plants, because you say they seem to love the fertilizer. You should certainly cut down on the number of times you fertilize. Alternate fertilizing with plain water watering, making sure you rinse off the plants well. Loosen the soil surface around the area that has the orange fungal growth and this will make the surface dry out faster and discourage the moisture requiring fungus.
