well i have been using the whole line of canna aqua with all the additives and its the best i've ever used(sfter using advanced nutrients,botanicare, and others

i use it with my bubbleponics and its amazing especially on the maintanance end of it
the ph is really stable does fluctuate mentally
i set the ph at 5.8 and it stays there

rhizotonic is great for the roots and the plants over all health
pk 13 is awsome add some just for one week just as the buds start to grow and watch them swell

the boost is awsome i use it duribg the last 5 weeks

and cannazym is amust as well
it basically chews up dead roots and feeds it to the plant

overall great but a little pricey but well worth the result if your gonna spend on it
