I've never heard of that product k-mag?? don't know if it will work. Why don't you order some online??I order stuff online on the time w a credit c ard an its safe as can be. For now get some epsom salt and mix it in at 2 tbspns per gallon, this will substitute for cal/mag for right now. You can also use it for foilar spray on infected leaves. When mixing new soil all you have to do is mix the lime in at 1 tbspn per gallon in the soil. thats it. it takes a little time for the lime to fully kick in and do it's thing so make sure you get some cal/mag. any other questions don't hesitate to ask bro.
