Someone sold you a bill of goods. Some of that stuff is fine, like the seaweed extract, for example, but most is just overpriced stuff you don't need. Look into Jack's a/b or Megacrop a/b (they're basically the same)-I mention both because you can usually find a discount code someplace. There are several threads here that tell you how to mix the two parts and what PPMs work for people at each plant stage. Why is a simple 2 part system better? Because all of your PPMs are a balanced plant food, you aren't diluting your feed with lots of unnecessary stuff.
