Dutch Passion Auto Critical Orange Punch

Eh so I got some autos I’m gonna do outdoors in the summer . I’ve got promix hp for soil going to be in 7 gal pots Nutients I’ll be using 444 all purpose and 284 bloom Gaia green dry powder so my question is I’m going to be premixing the soil hoe much if each do I need for autos I’m a newb btw haha I know autos don’t need as much nutients is why I’m wondering how much tbsp I need of each to start off mixing it in the soil thanks
