Flushing out before harvest-Soil System

Just wondering if I need to flush out my soil plants before harvest, as I hear it allows for a better taste after the curing process. I have not given them any fertilizers over the past two weeks but am looking to harvest within 3-4 days, what would be the best method of flushing if I do need to.

yes flush....flush a good amount....you want to get any remaining nutes, toxins, salts, etc out of the soil.......there will be enough traces of nutes and what not left over in your soil so you dont have to worry about harming your plant
