Mr. Mo said:Ok so I have been reading this and researching nute profiling a little. I understand it for the most part on a practicle level. In order to help me I just want to know who/how the target levels that are being used as a baseline were determined. How did one determine that these were the best target ranges for MJ?
Just Curious
I get all of that. I guess what I am trying to get is. I know that this formula is based on Mel Frank targets, which suggest a 100-100-200-60. My question is how did Mel Frank determine that 100-100-200-60 is the most ideal range of nutes for MJ?
