What nutes are a must for you? Reason I ask is I'm not new at growing but haven't grown in years and see how many new advancements there have been since I grew last (19years ago). My meduim is a coco/perlite/ castings. Very light maybe 10% on the casting. Anyways I currently use general hydroponics- flora micro,bloom,bro, cali mag,and earth juice catalyst which is .03-.01-.010. I want to know what you think maybe crucial from your experience on anything I may be missing or for the thread let us know your mix and watering regiment and the benefits from you comp.
