Ferts For A Small Soil Tank?

    Okay, I need some advice. I know that a few of these plants I have are water column feeders, meaning that they don't use roots to absorb nutrients. This tank has soil capped with gravel, so I'm wondering just how much nutrients would probably be in the water right now, and whether I need to dose with any extra ferts.

    I have 3 corkscrew vals, 12 very small and somewhat stunted bonsai rotala, six small anacharis, and a crypt. I also have a nicrew LED on it about 10-12 hours a day. I have seachem fluorish on hand at the moment.

    Dosing ferts into a dirted tank may be overkill. The soil will constantly be leeching nutrients into the water column along with any organic material (shed leaves, animal waste, etc).
