You've got some solid advise above. Some folks get confused when it comes to flushing. You should only "flush" if there's a problem. As in running 3x or more water through at one time to cleanse the soil per say. What everyone else says is right, just stop with nutes a few weeks before and just use plain water(which is what others call flushing) it can certainly be confusing sifting through everyone's experiences and opinions. i give em water for the last time and when their ready to be watered again is when I chop. Takes around 5 days before they hit the jars. Good luck
