I've been flowering for 10 days now and about to change my res and add my flowering nutes in,but i would like to flush for a day or so and wanted to use florakleen to remove salts build up and shit. I was told not to use any type of flushing agent on plants in an aero set up.This person said that it would dehydrate my roots.Can anyone verify or debunk this for me please. Thanx.
