Homemade soil for Autos?

Since you plant auto seeds directly in its final pot size. I'm trying to configure a mix of dry fertilizers and or amendments from what I have on hand to get a proper NPK. Should I aim for 444 or 555 and just use my Fish Emulsion for Veg and Hydrolysate and Morbloom during flower once a week. Or is there a better NPK.
Online there's too many NPK ratios. No one agrees on one. For veg for example I've seen 312 or 553. Lucas formula is 112..100N 100P 200K 100Ca 50 Mg 42 S. Lucas formula seems to be for hydro cause plants only take what they need from the soil. You just have to make sure you have myco and bacteria breaking down your dry ferts so it's available when needed. This is my understanding after growing organics. But again I usually grow Photos not Autos that have very short veg period.

I'm looking for amendments that will have plenty of N available the first 28 to 42 days and then have plenty P K available during flowering.

I have Alfalfa Meal, Crab Meal, Shrimp Meal, Neem Seed Meal, High N Bat Guano, High P Seabird/Bat Guano from Happy Frog, Fish Meal, Kelp Meal, Langbeinite, 15lbs Azomite, Soft Rock Phosphate, Epsom Salts, Gypsum, Oyster Shell Flour, Dolomite Lime, Diatomaceous Earth, Diastatic Milled Malted Barley, Blackstrap Molasses, Humic Acid, 25 lbs Rabbit Shit, 35lbs EWC, Recharge, Myco+, Dr Earth dry ferts 463, 394, 444, 222, Farmers Almanac Tomato dry Fert 848, Alaskan Fish Emulsion 511, Alaskan Fish Morbloom 0-10-10, Fish Hydrolysate 241.

I already have my mineral mix figured out. I usually run photos and cook my soil for a month. I only need ferts that release up to 4 months. I usually go Neem Seed Meal. 50/50 Crab and Shrimp Meal and Kelp Meal. But Neem and Crab is a slow release N. I don't want too much Nitrogen in flower.
Shrimp Meal is faster readily available 0 to 1 month. So should I just go 1 cup Crab and 1 cup Shrimp instead of 1/2c per cu ft each? I hope the Rabbit Shit gives me the Alfalfa hormones and of course EWC has readily available Nitrates.

I water in Recharge after I mix the soil up and throughout veg. Seems to work pretty good. I use Fish Hydrolysate in my watering during flower.
