How should i mix this all together?

I have 12 45 gallon smart pot grow bags, a shit ton of top soil and high grade compost, 12 cu ft perlite, and about 40 pounds of bat guano and earthworm castings each. How much of especially the nutrients should i put in? I came up with:

.25 top soil
.25 compost
.20 perlite
.15 bat guano
.15 earthworm castings

but honestly i have no idea if this will work well, burn the shit outta my plants, or have them not feel it at all.... so any direction even would be awesome! I've also considered teas but this would be a little more difficult because of where we are and other factors but if its the best way i will try it! This is my second grow, and first outdoors so i am working with very little experience here but i have a feeling this summer will be awesome!

that sounds like really good proportions man!i wouldnt change a thing,except i might use a bit more perlite and i would add lime at i cup per 5 gallons of soil,or 1-2 tbsp per gallon.

I mixed mine on the concrete floor in the garage.

well we have a concrete mixer to mix it all thank god. but is that dolomite lime ur talking about? ive only ever used #4 mix. haha do i dont know much about whats in a good mix. i also want it to retain more water cuz here in colorado it dont rain to much. haha will it suffocate the plants at what i have it? those grow bag are badass and breathe like motherfuckers.

If ur topsoil drains good ur perlite ratio is good espesialy in the fab. Bags.

its better to have more aeration,but this is outdoor so prolly just leave it then.

also what is the best way to implement molasses in my water? i have a well spigot. and not really anyway to store water to mix the molasses in... is there a hose attachment that i could get to mix it in and aerate the water?

Miraclegrow auto feeder thing or 5 gallon bucket open mind works wonders. U don't have yi have hydro store equip
