Is fpj a sufficient nitrogen fertiliser?
1. Can I count on FPJ by itself to support plants with nitrogen? 2. Can I count on FFJ by itself to support plants with phosphorus and potassium? If no, then what else can I add? I don’t want to add fish amino acids (FAA) as I want to grow vegan.
Top answer
From the KNF library
Drake's library gives FPJ and FAA different jobs. FPJ is Food: plant essence with hormones and enzymes. (Pure KNF Manual, p. 31) FAA is Fuel: simple amino acids that grow leafy material. (Cho's Solutions, p. 1)
Drake says you can overdo FPJ. Too much nitrogen overgrows plants and draws pests. (Office Hours Ep. 126, 39:37) One office-hours summary calls FPJ 'fuel', while the manuals give that name to FAA. The library disagrees with itself on the label. (Office Hours Ep. 41, 1:08:13) (Cho's Solutions, p. 1)
Plants need less added Fuel as they age, because they make more of their own amino acids. (Pure KNF Manual, p. 47)
For a vegan route, pick the plant for the ferment. Drake lists nettle for nitrogen and boron, and comfrey for potassium and phosphorus. (Office Hours Ep. 15, 54:03) Keep to one plant per ferment. (Office Hours Ep. 19, 50:59)
The library does not say whether FPJ or FFJ alone covers nitrogen, phosphorus and potassium. It names no vegan swap for FAA.
