DH, it's the standard representation of N-P-K nute ratios. Meaning 1 part N -to- 3parts P -to- 2 parts K. I mean this only as a constructive criticism, but you're still looking for that magic bullet that doesn't exist. Your variables are different, whethere it's different lighting or something as subtle as different elevation or average levels of atmospheric pressure that will affect transpiration, which in turn changes things. HB is not quick to tell you his exact numbers I'm sure because he even finesses them on a regular basis due to feedback from his plants. As you can see between all of the good growers no doubt all having good results in their environments that there is more than one way to crack this egg. You have a base to start from now, but from here you'll have to find what works best for you in your environment. Resorting back to the product labels for guidance was not what HB had in mind, I'm sure he wanted you to learn the art of reading your plants and acting accordingly...
Just make slow changes from what's working now. We are always here to show pics and provide feedback. It won't be as hard as you think, but somewhat of an ongoing process, especially with new strains and phenos. I am still honing my own skills, but the forums are great because there is always someone to help 24/7... Make sure you keep a journal of feeding levels, ec, lighting, etc. And keep filling this stuff in forever. That way if you want to run a particular strain again you'll be able to start out with what you already knew from the last time and your results will be that much better and easier the second round right from day 1.
I've seen your pics and know what a massive bodybuilder you are, and surely you understand that if I ate the same as you for a month I'd probably have to call the guys to cut a hole in the side of my house and take me out on a stretcher-lol. Plants are no different in that they vary the same, genetically and environmentally influenced.
