Algae is caused by imbalance. You've got your NO3 in order, but what about PO4? Could be too high or too low. Too much PO4 and the algae gladly oblige to grow on it. Too little PO4 and the plants can only use so much of the PO4, leaving plenty for the algae to grow on.
If your PO4 and NO3 are in balance (1 part PO4 to 10 parts NO3), then I'd next suspect Potassium. Flourish Trace supplies micronutrients, but your K supply might be a bit low. If potassium is the limiting growth factor, that leaves both NO3 as well as PO4 for the algae to happily grow on.
