People don't seem to understand that by flushing or leaching the plant of its reserved nutes that are held in the plants cells, causes the plant to yellow and eventually leaves die and this process cleans the earthy, funky tastes from the buds and makes for better burning canabis, you want to get chlorophyll out of the plant especially. If you time your flush properly, you buds have pretty much already reached their full potential anyway, so why not rid as much funk from the plant. I've smoked fresh weed unflushed and fresh weed flushed, and it was clear the flushed had better taste and better burnability.
