I think anything synthetic will kill the soil. I'm sure people do well with this water only but every plant is different so there is absolutely no way it can cover them all. My last crop would have been dead on the third week in this stuff. I am always absorbing info and watching grows to see what works and what doesn't and this stuff is to "universal" for growing pot. Now I did see good stuff happen with optic foliar and I bought gallons. I'm up for anything. Sorryl for the rant dcat and I am the least organic grower in the USA so I'm not much help either.
