Hi everyone can you help me with soil ratio please?

Hi everyone I am now planting my first set of autos and plan to feed with Gaia green living soil, worm castings, 4-4-4 all purpose and 2-8-4 bloom what ratios should I mix them at. I plan to fill five 5 gallon pots. Thanks in advance!

no experience with that stuff. make sure your end mix has ideal ph

and a bump if your still around
