Adding superthrive to the canna aqua lineup?

So I did look in the canna nute thread but couldn't find anything(so many pages!)

Ive got a&b(veg) and rhizotonic as well as cannazym. should i use superthrive ontop of rhizotonic or is it just for root growth and transplants?

I was told about tonight at the clinic and after what I've heard and read it basically doesn't have an exact ''use'' it claims it just overall helps everything it seems.

i use general hydro nutes, but i swear by superthrive. from my tomatoes to to the ganja. peace
