Cannabis plants don't need anywhere need as much P as they sell in nutrients, according to research done a while back by one of the nute companies. Farside posted that info on the first page of his grow thread.
I have found that the high K in MC doesn't lock out the N unless you start adding K boosters like Terpinator. I had to dial back the Si I was adding in stretch because the K in it was locking out N. And plants need more nitrogen in flower than most folks think as well, as evidenced by the graphs from Farside's posts.
I've grown a number of big frosty plants on this formula with no problems that can't be solved by upping the grams/gallon a bit. And I know a lot of growers doing the same thing, including Farside, MrSauga, Dutch, Professor Flora, and Homer Simpson who has these two trouble-free beauties:
And of course, my flowering three:
