I had the same when I was using 118 Watts for 12 hours on a 53 gallon tank. When I took it back to 70 Watts for 10 hours it got a lot better. I still get a little bit when plants reach the top of the tank, so now I'm going to raise my lights around 6 inch.

IMO it's no nutrient issue or CO2 issue, since my CO2 is already at the limit, using the fish as a limitation factor.
