i came up wiht an anecdotal test to see how much tar and crap was in my smoke
I'm no expert on this subject but ....
Received a sample of a few buds from a Canadian friend growing in heavily amended soil. It was almost like the nutes in the ground were not used up at harvest time, because it tasted like shit and we could not even finish a joint. Maybe it tasted like shit for a completely different reason though I don't know.
Potassium will kill off microbes, reducing the available N. It is not easily burned and remains in the ash. What does burn is hot and nasty. It is very water soluble and is significantly reduced with a couple days flushing.Bongjangles has it right
i like to force the plant to feed off of itself, I do this by cutting food
your plants should look like they have undergone seasonal change
the soil microbes stop activity at the end of the grow season in many locations so many plants are forced to feed of their own stores naturally

Getting rid of the green vegetative growth means cutting back on nitrogen. Nitrogen is the nute we want used up. P&K are supplied to the very end to promote flowering and flushed out at the end because they make harsh smoke.
