Dr Hornby or BioCanna?

Hi there i was wondering which nutes to feed my plants. I have been giving Canna BioRhizotonic since seedling and are now a couple of weeks old.

I was thinking:
1)Dr H Iguana Juice Grow, Dr H Iguana juice bloom, Dr H Big Bud and Organic B advanced nutrients

or

2)Bio canna vega, flora, bio boost, pk 13/14

If anyone has used or know anything about these products please share youre knowledge

I've used Bio canna flora, with some pretty nice results, needed to add a bloom booster but never got around to it...

the nice thing about bio canna is it adjusts the PH naturally, no need to add ph up/down if your using R/O'ed water...
