Feeding Spirulina

Hi  , I  am  considering  growing  Spirunlina  as something else  i  can  feed my  plants...   I   would rather  use  what i have on my land .   I  keep hearing  about the possibility  of using  compost tea  or  worm  juice as a  nutrient source  with  bicarbonate of  soda .  Has  anyone  successfully  done this ?  I  dont  really  want to  use  urine  as im on  meds ,  and im  not into  ordering  chemicals on  amazon  etc
Anyone  figured out a  successful  way to  grow naturally using locally  sourced items ?
Im  looking  for  people that  have   already   figured this out  
Many thanks
