Same way you provide nutrients in any other hydroponic system... soluble nutrients in water.

I like to mix powder fert in potting soil as it's set and forget.
As far as growing goes, hydro need not be considered 'harder' than soil growing, but yes, I will admit, you can take a much more half arsed approach in soil and still get some sort of result. You're much less likely to get away with it in hydroponics.
