Fortunately, some wise growers convinced me long ago that "weed nutes" are a complete scam designed to exploit the ignorance of the average weed grower. 10 bottles of shit to grow weed? Yea, fuck that.
Stick with something simple, like Dynagro or Jacks. Hell, even master blend produces great plants. The bottom line is that you don't need to spend a lot money on nutes, nor do you need to use multiple bottles of shit to grow some dank.
