Is there a possibility that CO2 is now the limiting resource (previously it was nutrients)? Since you don't have any fish, it might help to increase the CO2 flow and see how the plants respond. Do you have any idea what the current CO2 concentrations are (based on ph/kh), or do you have a drop checker (and what color is it)? Are the plants still growing well (even though they don't pearl as much)?
