GMSgrowsanswered grow question 3 years ago Canna is overpriced watered down crap like most. I have had way better results from floranova grow and bloom. It is very concentrated and a little goes a very long way. You just need to shake the crap out of it, then mix into your water until you reach the ppm you want to feed your girls at. No mixing, no guessing, as they are one part nutrients. I have grown over 40 different strains with these nutrients and it has been all my girls have need to maintain a very healthy existence. It is also ph stable. Being a one part fort there is no screwing up your mix. When I switch to bloom ferts, I also use Massive bloom formulation along with the floranova bloom
