"Flushing" or "to Flush", as defined by google is:
cleanse by causing large quantities of water to pass through it.
"flush the toilet"
Hydroponics can't be flushed, as you just dump the water and refill. When the term is used in growing Cannabis, it's for cleansing Soil and nothing else.
People are confused as to "Flush" by cleansing soil, and to "withhold nutrients" at the end of Flower, to break the Chlorophyll's cycle, and speed up curing.
With that said, chlorophyll is, in fact, the number one reason of harsh smoke or chemical taste. **Chlorophyll naturally breaks down*** as the nutrient uptake slows (also naturally) after it's lifecycle comes to a complete end. This is witnessed in nature all the time on all manner of flowers and trees.
The act of Flushing, for better tasting bud, is a complete waste of time. NPK has nothing to do with smoke quality. Leaves do NOT store nutrients.
The best explanation of why people forcefully withhold nutrients is to break the internal chemical chain of events within the chloroplasts, hence slowing or stopping the chlorophyll from being produced. Yes, this does happen, and Yes, your smoke may be smoother. But know this.... withholding nutrients the last week's before harvest, you're more than likely going to limit the full potential growth of your plant. Withholding nutrients is not the reason for better tastin and smoother smoke, broken down chlorophyll is.
Why anyone would want to hinder growth and yield for a week or two of time curing is beyond me. Why not just cut early, right? Why not quick dry, right? Heres an idea, if youre gonna spend all that time and money to grow, why not do it right, grow it right, feed it right, dry it right, cure it right, and not take shortcuts. Again, just an idea.
PS, anyone with a curious mind interested in learning more about the chloroplast within cannabis, here's a short clip on it. Expand your mind...., cheers.
