Red line is Jack’s 321, and Blue line is TSP Blue. These are both in my specific tap water so you’ll see a bump in Ca, Mg and S but both lines are using the same tap, so the delta is what matters:
- Super high phosphorus.
- Low Mg and S, do you ever add Epsom?
- Low Fe, do you ever see lighter green in veg thinking it’s N deficient?
- Zero Mo. I dunno but zero seems a bit low??
- 30% Nitrate / 70% ammoniacal. Ammoniacal is primarily used to control media pH when using in soilless…generally is not desirable for the plant at any stage of life compared to nitrate, so it’s more like a concession here to see so much. This looks like a peat based fert for tap water.
Thanks for sharing! This one was interesting.
