I have a 50 gallon. 2 x 96 Watt (I usually only use one of the 96 Watt lights), same filter, 3" all Flourite, Pressurized CO2. I dose the same as you have listed above except I only add the Iron once a week, 5ml. I am out of town a lot, so it is more common that I dose 2X a week instead of 3.
I have never had green algae, when I did have a small bit of hair or thread algae I did not feed for a week and the fish and shrimp cleaned it up. The plants grow great.
I think you *may* have an issue with getting enough CO2 into the tank.
