Got sick of tips curling and not knowing why so I spent about an hour figuring this out last night. Should have done this sooner. I've surfed some grow forums and not seen this sort of info maybe I missed it...
The calculations are from this site
So I have no idea about the accuracy of the numbers but the spreadsheet matches and the lucas numbers are from the same calc. At least now when I add a new bottle of "THEBESTPLANTCRAPEVAR!!1!" I can quickly see the effect on my NPK levels.
Is this useful, accurate, or maybe already out there in better form? Should I be matching my A and B program to the NPK ranges of the Lucas formula as a base starting gound? I'd like to add some other elements to this to keep track of potential toxicity levels but that'll take me a bit. For now I'm off to the hydro store for some P that doesn't touch my N or K ;)
Sorry for the zip can't attach xls and this is Office 2007.
