2 cups kelp meal
1 cup epsom salt
1 cup bat guano ( says 10-3-0 i think )
Thinking off adding humus as well 4 tsp?
Shipping here for bone and blood meal would be sooo expensive like 4x the product bought so would settle for this if i can get away..
If that is a commercial potting mix it ought to be close to PH neutral already and may already have calcium/magnesium. 3 cups of dolomite lime seems to be quite excessive, even if it were Peat Moss which is acidic I wouldn't use that much for your base quantity.
Also 2kg of perlite could be an enormous amount, I try to stick to using the same type of measurements for all amendments. So I would use about a third of your 23.5 gallons base, 8 gallons perlite.
Maybe you can source fishbone meal and or crab/crustacean meal in place of the bone meal? You could also use alfalfa meal in place of the blood meal if it's easier to source.
By all means add the humus.
