Which finned fixture are you using? The fugeray, the planted+, or the rayII?
My guess is that you are running high light, meaning you'd need injected co2 or to lower the light, and potentially used up the nutrients in your substrate and should start adding some fertilizers.
Also, in higher lighting, even with a dirt tank I've found you need SOME ferts just because there are certain nutrients that the soil doesn't have that the plants need.
