What about CO2? Given the relative low amount of nitrates compared to phosphates, that may be a problem. You could increase the nitrates up to at least 10-15 ppm.
Get in there and clean out as much of the algae you can. The dosing regime sounds ok...just adjust the nitrate to more.
I take your pH is low because of co2?
