Hey Shane, just a couple of things to throw at you. How long is your photoperiod? 96W on a 20 is a lot of lighting, and any issues with the water, ferts, CO2 etc is going to swing the pendulum towards the algae side. You said you started out real slowly, perhaps that last step was too large a jump with light duration, or something else. As far as the nitrites go, my guess is you weren't as cycled as you thought. If you're heavily planted, you know this won't be an issue. HTH.
