Tom doesn't post here anymore, but the answer is yes. The principle behind EI is to dose more than the plants need, so they never run short of any of the nutrients. Then once a week replace half of the water to "reset" the tank, getting rid of most of the excess of any of the nutrients. Flourish is only a trace element mix, so it alone won't work. But, you can use Flourish Nitrogen, Fourish Potassium, Flourish Phosphorous, and Flourish in an EI system.
