Doing my first no till indoor , almost complete my only suggestion is keep it simple make a couple of worm bins this alone in a matter of months will in deed put you in pace as for perfect soil
What i did as base was screened top soil with that i started adding leaf matter and compost almost 50 / 50 ratio then i added my own EWC and live worms into the equation added some , cardboard as well some fresh greens and have never looked back with only one tea made through out grow here are my 2 girls there healthy n green 6 weeks in and again water only
Its going to be trial and error unless you get your actual soil tested
PS started off with like 2 pounds of live worms now i have probably 150 pounds of live worms
Depends somewhat what the other 4/5ths are. I hate buying perlight due to overall % of cost but I am going with 33% atm. I was running 40%..... IMO / IME as a cold beginner heavier ratios of perlight where critical to the how to water learning curve.
i agree with the recommendations to the OP regarding increasing aeration, limiting EWC, and adding peat.
.
I'd be changing several things here, personally.
Since you seem to be content working in this percentage paradigm that I'm not quite sure I understand, but, EWC shouldn't really be more than 18-20% of the total volume.
Drainage and aeration amendments should be around 25-30% of total volume, depending on the type of aeration you are using.
I'd be adding some peat moss to the mix as well. Since you have about 35% being various soils, I'd be adding peat at whatever remaining difference exists in your desired 100% equation. I think it'd be about 15% peat moss.
Cannabis performs best in a light, airy, soil that drains well.

There's one entity that I always try to learn from because she is true and all knowing is mother nature.
Follow her lessons and you will not go wrong. Using the understanding that man has gathered from her and using it will bring you to your own living soil reality....
who wrote shit ?Jeez fella's...
....some Hammer of the Gods type shit in here.
The starting point is :
- excellent soil of my garden 25%
(a clay-ferrous soil with good Ph for the plant)
- earthworms humus 25%
(made from Horse manure by Californian Red Earthworm)
- perlite 20%
(from Germany)
- volcanic soil 10%
(from GuanoKalong)
what about the remaining 20% ?
i would be really happy if we can re-write together the starting point list...and complete the last 20% (i believe u understood correctly the percentage equation)
1:1:1: CSPM (Canadian Sphagnum Peat Moss) : Pumice/Lava rock : Compost
Amended per cuF with:
1/2 - 1 cup Neem or Karanja
1/2 - 1 cup Kelp
1/2 - 1 cup Crab/Crustacean meal
1 cup MBP (Malted Barley Powder)
1/2 cup Gypsum
4-6 cups Basalt
6-8 cups Biochar
The MOFO way
garden soil + volcanic soil = 35%
perlite (aeration) = 30%
EWC = 20%
peat moss = 18%
amendments (according to Xmo) = 1.5%
I think that is the gist of what I was saying. Those are not the exact ratios I personally use, but I don't exactly measure things in percentage as much as I do by volume. The base soil mix I use was developed over many years to fit my personal preferences.
I'm trying to answer your questions without completely changing the direction you are trying to take things - we all have our own approaches to making what works for us.
I would not consider things like azomite or other pelleted amendments to be part of the aeration equation. Add those type of items to a glass of water and give it a stir and watch what happens and you'll understand why. Many years ago when I first started growing in soil and transitioned from aerponics, I tried hydroton on the bottom of pots and found the practice to be unnecessary, ultimately.

I take a different approach. I would make that last 20% a good quality peat. Then I would send a sample to Logan Labs and base the amendments on what the soil actually lacks...not some wild ass guess based on ??? Especially this soil.
The peat breaking down does not make it more acidic, the plant taking base cations out of the soil is what makes it more acidic over time. You will have to reamend, there is just no way around it.
AMENDS : why so small amount ? or is it enough? tell me more about it if you can
p.s. Hydroton not on the bottom, ok...but what about to use inside the mix together with perlite ?
