Dude you really are starting to show your true knowledge. What don't you understand. Flushing is the act of leaching the plant in its final days. Done properly when growth has ceased and harvest window is open, you assisting you plant to do what is already happening. Chlorophyll is what makes plants darker green, and chlorophyll is bitter in taste and makes for bad burn ability. The more you rid/flush the plant the lighter in color the bud will become, and if you don't time the harvest properly your sugar leaves can and will turn yellow and die, at this point you've flushed for to long, only because people don't like yellow buds obviously, but in truth yellow buds would mean less nutrient present in the bud. It takes me back to why people that have grown in pre fertilized miracle grow, when they have to wear goggles to cover their eyes from the snap crackling nutrient filled weed their smoking. All that is is they've chopped their plant be for the plant has realized it's fate and prepared to die and, by waiting it could have all been averted if the person would have waited for the stems to hollow and stop up taking water, the plant will canabilize itself, even with nutrients present in the root ball.
