SO my plants have been steadily losing leaves as they yellow and die. First showed up as spots on my last crop. THe problem occured when i buildt my new flowering room. At first i thought it was a magnesium def so i nadded calmag to my regimentwith no results. I use CAP ebb and grow with co2 generator. I run my ppm at about 1200 and ph around 6.0. Im currently using the lucas formula with gh floranova series as well as floranectar, h202, cal mag and koolbloom. The temp in the room stays 85 with lights on but its my understanding that warmer temps are encouraged when using co2. my res temp is at about 75. I was told that a chiller would be a good idea so i could keep my res at 60-65F and then the plants are able to take up the nutrient? Just bought a chiller looking for some input or similar experience. Would love to hear your thoughts or questions on the matter.
Thanks
