Yeah I`ve used the standard Canna coco A+B, with PK13/14 being the only supplement apart from rhizotonic earlier on and sometimes a little superthrive.
I`ve always given the PK13/14 @ Canna`s recommendation, ie. 3 weeks before harvest for 1 week, but if Canna have changed their recommendation I`d assume they`ve done exhaustive tests to find a better way. I do wish they`d make their information easier to find though as I cant find out much about it, and their website is a bit crappy.
