A complete nutrient profile can be manually extrapolated from this data by multiplying the actual quantities (in ml/gal) of each GH component you used in your mix by the ppm values shown for that component. Or you may prefer using the Profile Calculator instead, especially recommended if the guaranteed analysis has changed over time.

It should be noted that the General Hydroponics Flora Calculator found at their web site hasn't been updated for some time to reflect the changes taking place in their products over time. It also uses volume/volume as the basis for ppm values instead of weight/weight, as their labeled percentages and the above figures do.
