are you in hydro?
I am not a big fan of flushing, why starve the plants? I usually give one day or two tops, but change the water 6 or 7 times over that day and keep the water running as much as possible - you could do this for a day and that will clean the plant as much as it needs to in my opinion - as such I test it, when the water from tap is the same EC as in the tank after running it for a while, its job done
