You mean to flush out the nutritions? You use DWC so around 4 days pH 5.7 water without nutritions would be enough for the plant to use its build up nutritions. Just change the water completely everyday. If you do this for only 1 day than you end up with nutritions in your end product.

I didn't know what flora Kleen is, so I just did some research. This is what I found: Flora Kleen flushes the soil of nutrients and salts that the plant didn't use yet. Most people who have used flora Kleen for years say to only water your plant with pH'd water for at Least a week before you use flora Kleen, since flora Kleen doesn't actually flush your plants. It looks like not flushing your plant before you flush the soil will make your buds taste gross. A lot of the people that did this stated they threw their harvest away because it was so nasty. As I said before, this isn't information from my own experiences. This is what I found after I did some research. I hope it helps. Good luck!
