Good question...exactly how much Si does a cannabis plant "want" as opposed to "require" or "need".
At the end of the day, it comes down to how much Si "I" care to have in the plant, cannabis will easily absorb a hell of a lot more than I care for.
Having run the gamut of zero Si, all the way to waaay too much, I'll stick with using it the first week of flower, in my flowering reservoir. There seems to be plenty for stretch, leaving the remainder to be absorbed during the remaining weeks. (Haven't dumped a res, mid-flower, in nearly 15 years)
It's interesting, I rarely run across 'frangible' cannabis these days, not since a couple years after Si hit the cannabis boards. Certainly nothing as frangible as mine. I've also noticed the average cannabis user/grower be surprised when they see my bud crush so easily.
Apparently the frangibility I enjoy is usually only seen with over-dried cannabis. *shrug*
