Details: I am growing several different strains in 2:1 coco/perlite. They are getting fed Jack's hydro, Jack's calcium nitrate, and Epsom salt. Mixing 5 gallons of nutes at a time using RO water with 18 grams hydro, 12 grams Cal nitrate, and 6 grams Epsom salt. All plants are being fed via Blumats from a single 13 gallon reservoir. They never receive straight water -- nutes all day, everyday. These plants are being switched to 12/12 today in a 5x5 tent running about 700 watts of led strips (500 overhead and 200ish from side lighting). More side lighting will be added soon and overhead wattage will be increased. Total wattage will be 1000-1200. I have only 1 Cookie Wreck plant and it is showing magnesium deficiency plus the new leaves on all of the plants seems lighter than past grows. If I get home early enough to get a pic I will post it up later tonight. Should I up the amount of all nutes, and to what level? Or should I just up Cal and mag nutes, or just add some calmag?
