Never heard of them before, but their stuff looks pretty legit. It seems to mostly be stuff you could purchase individually and combine yourself at a lesser price, though they do use 3 species of worm castings, and 3 of guano, which I think would introduce more beneficial microbes than just using 1.
Their bloom formula looks to be considerably light on N and K, though the ratios on the grow are pretty good. I would mix them together 50/50 for flower myself. Also not sure where Mg will come from.
Looks good, but probably can't be used as a stand-alone fertilizer.
