His recipes are very close to what i do too.
Except perhaps the P levels, which he uses 1,5 to 2x more than me.
I usually prefer Going a little bit lower, as P is strain dependent, but never saw an article pointing more than 45-60ppm during flower, and 15 to 30 ppm during veg.
Bruce bugbee says 15 to 30ppm to some strains, and near 45 to others (flowering)
I would strongly advise to raise it to higher end as the buds grow bigger, for the sink effect.
Guess we are all going to the same directions, worldwide, makes me pretty happy to know others are applying similar formulas.
