I don't believe that switching out the 10,000K for a 6500K will make a difference. I would kill some of the light, though. Run just the 2 96w bulbs until you have a good balance. That's still over 4wpg and if you don't get your CO2 levels up well over 20ppm, nothing else will matter.
Put simply, you're providing more light than your plants can use, given the availability of CO2, so the algae is glad to use what they can't. Once you get your CO2 levels up, (get a pressurized system), then you'll need to start increasing your PMDD regimen.
Don't be discouraged, though! All this work is worth it in the end! You'll have plant growth like you've never imagined. You just need to get things in balance.
