I was a Botanicare guy for years in soil. All I ever needed was grow and bloom. Cal-mag is good too. I use Liquid Karma, but only because they sent me some free samples last year and it was included. I would never buy it. Maybe that stuff is necessary in hydro, but I find the 10 bottles these nute companies tell you we need are a waste of money. I've since moved on to dyna gro and couldn't be happier. Still like Botanicare though I'm finishing off the bottles in my vegetable garden.
