Anyone familiar with Mother Earth Meal Mix® Grow?

Was piecing together my own soil recipe and came across this:


Looks like an amazing mix to go with my base of promix, ewc and insect frass. I was wondering if anyone has any first had experience with it?

According to the package it consists of:
Feather meal
Fish bone meal
crustacean meal
alfalfa meal
neem seed meal
kelp meal
dolomite
gypsum
langbeinite
basalt
potassium sulfate

For context, I'm thinking of adding it to my current mix
1 bale promix mp
5 gallons ewc
1 gallon frass
1.5 gallons mother earths meal mix grow
3 gallons perlite

Once i use up my current stock of promix and perlite, i plan to switch to:
15 gallons peat moss
15 gallons compost
18 gallons rice hulls
5 gallons ewc
1.5 gallons mother earth
1 gallon frass

Sorry, i messed up that final recipe, but can't edit the post. After i use up my current amendments the mix I want to switch to is:
25 gallons sphagnum peat moss
15 gallons rice hulls
10 gallons ewc
2 gallons insect frass
2 gallons mother earth meal mix grown
