How old is the tank? What temp bulbs (Kelvin rating) are you using? With that much light I would be dosing ferts (Ni, PO4, NO3) much more frequently. I would also consider adding other ferts than just florish. I don't know if Florish has Nitrates, potassium and phosphates that plants have to have to thrive. I think C02 is a must for that much light. I would do some massive water changes coupled with water testing to get you back on track.
