Hey Foigwtd I was talking to DaBaracuss and he had some information about the CalMag i would recommend...I would not recommend using the above formulation due to the Urea in the mix, as well as the HIGH nitrogen. The magnesium is a little low at 1% in the MaxiPlex; the one i recommend has 2% Mag, 3% cal, and 2.2% organic based nitrogen and i would use 5ml/gal during early flowering and then ramp it up as you get into flowering and increase the phosphorus used...He said he would post something on it today...
