A nutrient rich substrate is always a bonus. Don't get me wrong. Just remember when the nutrients in the substrate run out, where else does the plant feed? A good substrate with a high CEC will draw in nutrients from the water column to a point of saturation and equilibrium and release them when the column is low.
