I have not used canna but I would mix as they say and have a good meter to run the schedule. You may not find much on search because most use GH nutes. Most nutes are so close to the same and tested on MJ and GH is cheaper. I see the same results useing the lucas formula which saves me on GH, only use micro and bloom the whole grow.

Schedule is just raising the nutes as they go into flower. Some strains can take alot more than others so you must know or learn what your strain can take in PPM's. A good meter is a must.
