Coco Bloom Booster

I've had a go with the search function, but couldn't get an exact answer.

For a coco grow using Hid, canna A+B, b'cuzz coco booster, PK 13/14, Nitrozyme, what bloomer would you recommend out of

Canna Boost

BioBizz Top Maxx

B'Cuzz Coco Bloom

These are available locally. Is there much to choose between them, or are there any better alternatives?

cheers

i'm using canna boost at the mo, haven't had a harvest yet with it so don't really know how good it is, but quite a few people i've spoken to say its good. One of my plants started getting bleached from the light, boost works by messing with photosynthesis so i cut down the dose and its fine. seems to be good. My plants seem to be developing quite fast but thats probably a mixture of things. can't really say much else until i harvest, its meant to make them sweeter as well
