Here's my suggestions:
Use Roots Organics Original as your media. You never hear of people complaining about it, ya sure can't say that about Fox Farm.
I'd go up to 5gal pots....especially for a first grow.
You can try the Dr earth, didn't say what ya have, or you can go very simple. You have more useful and valuable things to learn how to do without worrying about applying nutes 2 weeks ahead of the tome it's needed and what to use. You need to learn how to water properly and how to manage your environment to keep it in line with the VPD needed for the stage of life of your girls.
I would get the single part MegaCrop and use
pop22 low dose feeding schedule
. It's
SIMPLE!
Any major brand mycorrhiza
Boost
Maybe some
good quality Earthworm casting
Get a good grow under your belt and go from there. This way you can learn how to manage your environment without other thing getting in the way. It also keeps you from getting into buying a bunch of different amendments and not knowing how to properly use each one.
Here's the result
s from my first ever canna grow with MC being my main nute. I did use my other organic methods also, but MC was the main nute..
That's from one cheap Linda Seed GG#4 girl

I'm a 30 year organic farmer. I'm mainly a living soil kinda guy. Container growing is new to me, so I had/have to learn the nuances of that. Once you learn the basics of organics, it's fairly easy to adapt to various situations.
Organics and living soil can make a quite easy and productive grow, but it takes prep before the grow. Your media need to "cook" in a tote before using.
Just don't get into buying a bunch of different nutes and other things and thinking YOU know what needs at that moment.
Most importantly......................Jf you have ANY question..................ASK!
