Try my dutch organic beastload one time, piles of chickenshit and fermented nettle tea. Waist water from a pool of grass carp if you can get your hands on that. And start a compost bin at same time as starting plant, there only put in eggscales and fruits, so not too much/no green plantmaterial(vigs are always welcome) just add a bag of compost in de bin on outdoor soil, maybe manually add worms to start the proces if soilconditions are harsh. This compost will be full of the good shit your gonna add in flowering period. Nice grows btw!
