I was just joking around, mostly, as grandmasterlevel is apparently an excellent cannabis farmer from what I can/have seen - that part seems pretty clear. He's said his name came from the AN line of nutrients "level" that goes by the same 'name'. Anyways...
I remember trying it (to the level or instructions that gml has given), at least once, maybe more (again, I mean the specific heavy 'flush' style) and I
think this was in coco. The amount of excess salts/nutrients that came out with the initial runoff of each "flush session" was as ridiculously high as suggested it would be. I don't think I've seen that much fading colors before. And it was "smooth" and burned white/light grey ash.
Since then I've seen varying amounts of flushing to not flushing at all achieve the same smoke quality, but not the fading colors. But nothing is really consistent among the grows - not even medium. So there's some pretty useless information, hah. Could be better drying and curing, or just experience in general.
I wonder if there's something other than npk changes going on; enzymatic, fermentation, a head start on chlorophyll breakdown - I don't know.
Sorry for the tangent
