I can't find cal/mag anywhere near me. It sucks, next time I'm gonna throw in some dolamite lime and mix up the soil with another brand with my ffof. I had buffer tabs from sannies but I started my dirt like 2 weeks earlier then planting. (u know trying to b prepared) come to find out, I probably should have just waited and done it the same day I planted my germanated seeds into the finale pot.
Live and learn I guess, expensive lessons to learn also hard lesson..........
