recently build a diy ucdwc/ ebb and flow hybrid. I also found an unopened bag of jacks professional high performance nutrients (25-5-15) at a flea market for 5 bucks and bought it. I have done research and people have really good things to say about jacks nutrients, although I know that it is not specifically geared toward cannabis. It is water soluble and has the necessary elements for growing plants. I just wanted some thoughts and opinions on the nutrients. Should I supplement with some thing else? Can I use this for veg and bloom? Is it worth it to use at all? I really don't like to spend money on nutes and they seem very overpriced.
