The Jack's is working great so far, the plants are showing fewer issues than with the Botanicare. The leaf spotting that I was seeing is much less and stopped after a nute change, I think a mag deficiency. Overall the Jack's is easier to use because the pH is very stable, I have stopped needing to use pH down. Also there are a lot less things to mix and measure. The water is clearer after 2 weeks when I change the nutes, not like the scummy mess after using Botanicare. My results were very good before changing and I still have not finished a complete cycle with Jack's, but my impression so far is that this stuff works great and I will probably switch over, but keep adding the Aquashield and Sweet. Next batch I'll try using just Pondzyme and no Aquashield and see if the roots remain healthy. I might try molasses instead of Sweet, still looking into that. Since I flush for a full week there should be no taste difference, just nice healthy flowers, but I will pass around the results for opinions. So far everything I have grown and shared has gotten great reviews except a couple comments that the Northern Lights is too strong, def a night time smoke. Stupefying is a good description of the effect.
