I'd grab the hpcc if they have it but any of them should help to cut it.Should I get bx or hp? I have a giant bag of #4 perlite so I can always add more. Didn't know if it'll matter for this
here's the P and micro amounts for a cubic yard/ 202 gallons
580 grams Triple Super Phosphate needed per yard
Borax 8 grams needed per yard
55 grams Manganese Sulfate per yard
31 grams Copper Sulfate per yard
42 grams Zinc Sulfate per yard
it's going to be a salty mix, don't test plants in it you if you are not ready to see them die, lol.
