I recommend building supersoil and making it living. Then, you don't need to worry about nutrients after a couple runs. But, that involves amending, re-amending, composting worms, soil mites, cover crops, and big buckets or earth beds.
So, i'm going to say, grab Advanced Nutrients 3-bottle pack. Grow, Micro, and Bloom. You'll probably need to get a bottle of CalMag, too.
If you want to use organic dry nutrients, the Down to Earth stuff is great. Crustacean meal, kelp meal, blood and bone meal, bio-char, oyster shell flour, basalt, gypsum, malted barley seed, and neem/karanga. It's always good to have langbeinite handy, as well. That stuff is amazing. You can even get most of these in one mix called Craft Blend, from BuildASoil. They also have a YouTube channel with loads of free information about starting and maintaining living soil in pots and earth beds. Nothing touches nugs that are grown in this setup, in my opinion.
Hopefully this isn't information overload for you.
I hope this helps.
