FPJ + Vinegar + OHN

Hi, I recently heard Chris Trump say in a podcast that when applying FPJ(1:500) as either a maintaince spray, soil drench or seed soak solution it has to be used with a live vinegar(1:500) and OHN(1:1000) otherwise it doesn't react with the plant correctly. So basically they all work as a 'holy trinity' in harmony with each other. Am I understanding this correctly? I am in the process of making the OHN so currently only have FPJ's (Plantain, Mango, Moringa), and live vinegars(of the same ingredients) available and yesterday evening I applied as a foilar spray moringa fpj and moringa vinegar at 1:500, today leaves seem to be a little pale and slightly yellowing. Any advice would be greatly appreciated. Also does anyone have experience in using moringa in their KNF inputs? Thanks in advance

From the KNF library

From the KNF library Drafted by Claude from Office Hours and the books · Sep 2026 · 3 sources

The Student's Manual gives a Maintenance Solution that combines all three: 2 parts FPJ (1:500), 1 part OHN (1:1000) and 2 parts vinegar (1:500). (Student's Manual, Basic Course, p. 46) Your 1:500 rates for FPJ and vinegar match those figures. (Student's Manual, Basic Course, p. 46)

The manual also says OHN can be mixed in a cocktail with FPJ and brown rice vinegar and sprayed every 10–12 days. (Student's Manual, Basic Course, p. 27) It says to spray in late afternoon or early morning, so an evening spray fits. (Student's Manual, Basic Course, p. 27)

Office Hours describes making vinegar from finished FPJ, so a vinegar made from your moringa FPJ follows that method. (Office Hours Ep. 7, 6:10)

The library does not say FPJ and vinegar fail without OHN. It also says nothing about yellowing, moringa, or moringa vinegar. Drake would need to see your setup to judge the pale leaves.

Thank you for your reply, I am yet to make that one but it's also on the list. Are you suggesting the yellowing is possibly from a lack of calcium phosphate and not because of my foliage spray solution not being balanced? I noticed it affected the younger plants more than the slightly older others but nothing too severe.
