seriously read the thread all the way through on cheap alternative nutes for plants. now I dont work for anyone I am retired Navy who switched to only using extracts and smoke a bowl every day.
But Jack Pro is the fertilizer yip for discussion but more than that the way it is explained and how the numbers of ppm per grams of this that and the other made it very ez to follow........ Just my HO 2c
Much respect
