Not sure what kind of scale you are growing on, but I like being able to build and then maintain my soils from the beginning with individual amendments. I know it's not as feasible to do on a larger scale, but being able to work with the individual amendments just adds to the joy of growing for me making it more so my own unique environment. There seems to be an endless way of going about things to achieve the same result of a successful grow. From specific amendments added/top dressed to the soil to ferments to teas, it's all about putting those nutrients into the soil and then letting the microbes handle the rest for us. The compost/micro life in the soil is what will turn whatever method/amendment we add into something useful for the plant.
That said, I have bought down to earth individual amendments before and have been happy with them. Not really familiar with any of the other brands/blends mentioned, but I'm sure they will all steer you down the same path of success as long as everything is healthy and thriving in the soil. I like to think this whole organic is hard to go wrong as long as things are done without abusing any one specific thing.
Sorry not much useful info in there, just my two cents on the matter and a little rant for the day. Wish you all success with the grows though.
