Hi GC community Im wondering im starting my micro grow and im going to use black gold organic potting soil. Will i have to use some kind of fertilizer also? Or are all the nutrients i need in the black gold , cuz i know it has worm castings etc. I was looking at lay miller alaska fish fertilizer. Dont want to have use it if i dont need it. Also my water. Tap water thats been left overnight good? Thanks fellow tokers \t \t
