I am using it right now. It does what it is supposed to do. FYI, Advanced Nutrients is the best line on the market. Ask any professional grower and they will tell you the same thing. There is a lot of BS on the internet regarding cannabis and how to grow it for yield, quality and all the rest. The fact is, AN is the best fertilizer on the market. Bar none. Some of their nutes are pricey. However, they always perform as advertised. If price is a factor, my suggestion is to buy in bulk. Connoisseur is about the same $$ as Sensi Bloom when purchased in the 4 litre size. Good luck.
