Sorry to say it isn’t as simple as putting fertilizer in dirt and you’re feeding your plants. Organics need microorganisms to breakdown organic molecules and release the nutrients. You can have all the ferts in the world, but without the critters it will never be useful to your plant. If you’re growing outdoors in the ground, then you (probably) have tons of microorganisms which will break down your organics. But if you’re indoors in a pot, then most likely your soil won’t have any (or very little) microorganisms. Here’s a little cut and paste on soil biology;
If you’re indoors, you’ll need to figure out a method of creating a “living soil” that is a combo of the microorganisms and nutrients. You can do this by using garden soil, adding compost, making compost teas, or buying “beanies” in a bottle - with the later being the most popular with tent growers. I’m not an indoor grower, so not wise on store bought microorganisms, but fair warning that it’s a fairly complex subject and weed sites are notorious for lousy bro-science. So while there are some very knowledgeable growers here, suggest you also look to other agricultural and education sites (like this
