Homebrew indoor soil

I mixed up a bunch of soil about a month ago, using the following recipe:

1 part (1 gl-+) peat
1 part vermiculite
2 parts perlite
1 cup lime
1 cup bone meal
1 cup blood meal
1/4 cup mag sulphate
1 cup+ worm castings
1 cup+ mushroom compost
1 cup+ black cow compost

Batched into fills for roughly 7gl baskets with poly 'grow bags'

So this stuff was pretty hot... I put it into the pots and mixed/wet it, and wetted/churned it 4 times since. Do you think it's still too rich, or am I GTG for some fairly healthy month-old babies? They are looking for a bigger home...

Thanks...

I am not saying what you are doing is a bad idea, but I am curious...how does that compare to just buying foxfarm soil or something like that?

Probably about 1/3 to 1/2 the cost of FFOF.

All for nothing if the stuff kills my $10ish per seed babies though...

i've haven't done any soil mixing yet, been fine with some of the cheap prepared stuff
but this looks like it's red hot, that 1 cup of blood meal should fry just about any sprout
maybe i'm not reading the proportions right, but i'd try one seed as a test run
