I feel like the only thing that is a bit expensive in their lineup is the shooting powder. Other than that...their shit rocks. I'm using Floranova one part now just for simplicity....but H&G is a fantastic nutrient lineup...
And probably a user error this time around. like others have said...lower your EC...2.8 is retardedly high!
You def. were not duped. Those nutes should last you a while.
