I have been growing all sorts of things for 30+ years and seem to remember the bloom booster fad was initially geared towards ornamentals.Science is real; anything over 50ppm P is crazy and just ends up as waste.
Where exactly is the widespread P deficiency you claim?
The Phosphorous craze is cannabis-specific with no basis in reality.
It's much better to get nutritional info from general hydroponic sources not focused on cannabis.
I remember seeing all the big AG do it first, Shultz, Miracle Grow, Jacks Classic, Scotts...etc. My perception may be completely skewed....I do smoke alotta dat green after all.
