There are 3 versions of Tribus Microbes: Veg; Bloom; and Original, which is full cycle. I also buy direct and they offer better prices. I recently purchased their fish ferts for veg and bloom. I thought it was a good price compared to what I had been using. Just using the veg so far and I'm happy. It's recommended to ph it to 6.2, so I dusted off the old pen and got a bit of organic ph up to raise it. Believe me that feels weird but the company suggested it and I think it's a good idea to follow that in this case.
