Hey billy
I never tried their folage spray cause they say you got to buy their saturator and when I looked it was way to much money. My last grow I ran into a magnesium deficiency. So this time just before I flipped them to 12/12 I used some epsom salt on them, followed with some regural water spray to ensure that the left over dried epsom salt got absorbed into the leaves. Also I think that the ductmaster gold series does not have enough cal/mag so I am adding general organic cal/mag into their diet.
I go by the duct master calculator I havent ran into any problems but keep in mind that since I am adding additional cal/mag I always only use 70% of their recommended intake cause the cal/mag adds the rest.
