Howdy Farmbuck. Lovely pictures (as always!). I started using the Cali Magic on my current grow. I thought (or didn't think enough!) that there was a sufficient amount of calcium and magnesium already in the 'hard' city water that I have been using. Well, (no pun intended), I was wrong. The plants are doing better than before, they seem to be more potent than the last time that I had grown from these seeds, and even the roots appear to have done better! In a couple of weeks, I'll start to harvest and tell for certain. I'll continue to use the Cali Magic on my future grows.
