Fertilizing blackcurrants and gooseberries small garden

Hi I am planning to grow some black/red/white currants and gooseberries. In my garden soil is in not the best condition. I am just starting making ohn + I am planning to use fpj and lab along. I wonder if fish meal + kelp meal + maybe insect frass would be complete fertilizer ? Ohh and I am making my own wormcasting aswell so I would be topdressing plants with it aswell, but its not big amounts :) Gooseberries are quite heavy K feeders but they also don't like to much nitrogen. I been planning to use chicken manure pellets or fish blood and bone but I am not sure is it good idea because of all antibiotics etc. What do you guys think ? In the future I am planning to collect maybe some imo and make my own faa.

From the KNF library

Drake recommends matching nitrogen to the plant's stage. Cho says nitrogen given as base manure prevents root settling and lowers absorption (Cho, Theory, p. 117). He adds that this does not mean using little nitrogen. It means adjusting the amount and timing (Cho, Theory, p. 117).

Once plants turn to fruiting, Cho says to control nitrogen (Cho, Theory, p. 117). He assigns phosphate to flowering, and potassium and calcium to ripening (Cho, Theory, p. 117). Too much nitrogen from FPJ causes overgrowth and draws pests (Office Hours Ep. 126, 39:37).

  • Prepare the new bed: ridge it, soak biochar in fish amino acid, add IMO4, water in maintenance solution plus minerals, then a Jadam microbe solution (Office Hours Ep. 20, 19:36).
  • Spray FAA at 1:1000 in the vegetative stage and 1:2000 later (Office Hours Ep. 32, 32:31).
  • FAA holds simple amino acids that assist leafy growth (Pure KNF Manual, p. 31).

The library does not say whether fish meal, kelp meal and frass make a complete fertilizer. It also says nothing on chicken pellets, blood and bone, antibiotics, worm castings, or gooseberry potassium needs.
