coco nutrients help me out

hi does anybody use canna coco nutrients just wondering if anybody could tell me what strength to start with my cuttings when i first add the nutrients

Most start nutes off light 1/4 mix or about 100 ppms. I use ppm's and add 50-100 each feeding untill I hit 780-800 ppm's reading at the start water 220ppm nutes 50ppm = 270ppm's first feeding.
