In case he didn't already know, Canna has a nutrient calculator that outlines basically every phase of the plants lifecycle here:what is lights off temps? i personally would either go up to 24/0 or run a heater during lights off to keep day/nite temps pretty close to the same.
i've never used Canna but i would think maybe 0.5mL of each A and B per gallon would a good light feed to start with. maybe 1mL of each depending on what EC that gives you. somewhere around 0.2 to 0.4EC should be plenty.
