i don't like the ratios they use... seems really high in N and really low p/k for "grow"
i don't know how they calculated ppm, but it's a weird number... when i do the math i get very different things as you can see below.
in order to get enough p and k, i'd suggest something along the lines of this:

And in bloom i'd drop N down to 110 ppm or so but try to keep the rest roughly the same. Minor adjustment needed.. local vairables cause some differences.
There's probably a way to make any of the 'base' powders work, but you'll need the pk boost component even in vege, despite what their feeding schedule says. The instruct a dose of P that is 17 ppm... that's 1/4th of what it should be.
