I refuse. I have been using nutrients like Jack's for a long ass time, and this time around I'm trying to keep it organic. I do have compost and more one shot available, and I am also willing to use liquid kelp. I think thats "complete" enough.
How much langbeinite should I add in to my feed water during flower? I am growing in Coco coir amended with one shot nectar for the gods with no other nutrients.
