Reduce your light time or turn the power down or both. If the thing that changed is the light. I would back pedal and see if that helps. I wouldn't start putting chemicals in the tank till I tried changing back the last thing. Water changes never hurt too. I had a bloom in my tank and I cut my duration back by 2 hours and strength down from 50% about to 25-30% and in a few weeks (about 3) with regular WC it went away without nuking the tank.
