Canna Coco A+B is one of the best base nutrients out there. Its so clean and produces well. I've had great results in flower going with 5 ml/gal part A and 7.5-8 ml/gal part B. Some strains don't need that much nitrogen so backing off part A works well. Recently mixed in 5 ml/gal of Hesi Boost and it worked very well with barely any leaf tip burn throughout flowering.
Many people would sooner die than think; In fact, they do so.
