whats the NPK of your soil, and the secret stackerI only use cal-mag and humboldts secret stacker. I just started using humboldts secret stacker though, i ran out of big bud and humboldts had next day delivery. My intention was to stay away from nitrogen by only using bloom nutrients and cal mag but cal mag is the only source of nitrogen i can think of that caused the toxicity
