Short background,
After mixing 80 gallons worth of Jacks 321, after about 30 days of using the concentrate I had to apply way more concentrate to get the desired EC level. The Jacks formula and epsom concentrate was in its own bottle and the cal/nit in the other. The Jacks/epsom was the jar that I had to apply up to 4 times the amount than when I started to get the same ppm.
I saw a definition of this in an abstract involving pig slurry concentrate. The abstract explained how the other nutrients broke down over time while retaining the original amounts of phosphorus. This abstract was either found here or some other cannabis growing site.
Anyone know what I'm talking about and/or or can share an article to this?
