What have you been using as a Top Cap over the potting mix? Diana talks about not using anything with a small particle size, because it prevents the return of nutrients from decaying organics to fall back down through the top cap.

+1 on the overfeeding. Fish food has everything a plant needs, but it must be allowed to fall into the substrate.
