Their site has a fertilzier calculator on it, right above where you bought the fertilizer packages.

As someone suggested, lower it to 2-3 bulbs and shorten the time on it.

You have more lights on a longer cycle than I do on my reef tank. I have 2x39W T5HO on 8 hours/day especially your plant stocking levels isn't that much.
