Medium soil mix.

Hello there grow fam! I was wondering what sort of soil mix I should? there's just so many options out there to choose from. it's really hard to pick. but I was thinking I'm going to go with pro-mix HP along with worm castings and perlite and then dry amendments like Gaia greens 444 and 284 bloom. He all think that's a reasonable mix? I'd love any suggestions, I'm completely open!! And I was wondering what the percentage of each one I mix in?

Yes that sounds good. Maybe get a dry amendment that give nitrogen. Read the directions on the labels and use the recommended amounts. The items you listed some may argue are all you need. Next you need a pot to put it in.

I just use fox farm ocean forest and cut it 50/50 with perlite for better drainage, then I use Flora Nova veg and Flora Nova bloom. I only tried dried amendments once and learned not to follow the recommended dose fully, because I gave my plants what the nutrients recommended and it fried my whole garden in one day
