I'm using something similar in terms of dry nutes for hydro called Masterblend 4-18-38. I use it with cal/nit and Epsom salts at a mixture of 2/2/1. From the research I've done on Jack's it seems most people are running it at 3/2/1. I understand the two fertilizers have different ratios of minerals but in theory wouldn't their ratio of fertilizer to cal/nit and Epsom salts be the same? Obviously everything else in a given situation would have to be similar as well I assume. Do you think I should stick with my 2/2/1 or switch to 3/2/1? If anything was lacking in my 2/2/1 solution compared to the Jack's 3/2/1 solution, what might the symptoms be visually or in plant growth? My plants did well but they could have done much better and I was thinking this might be an issue to look into. Thanks!
