How Much Cal/Mag for MY PKA Thanks!!!

I was pretty certain that the Botanicare Cal/Mag was 5ml/gallon, as it's listed on the bottle.. for soil-based gardens, anyway. (If memory serves) You may wish to start with what the bottle says, or start with 1/2 of it.. and work with it until you find with what your specific strain(s) like the best.

Just my .02

I am using FFOF. My strain is PKA. Thanks Figong!!!!
