Sauce, you might find this useful, YMMV. I used this chart to help draw up a feed schedule for the plant i just started. I adapted it based on the specify nutes I'm using (I don't have any of those really fancy nutes with the cool names), but this chart is good to show when you need less/more of nutes. For example, you'll see that Grow Big has a high concentration in weeks 2, 3, and 4 because it has high N content. Boomerang I believe is 
version of cal-mag and you'll note it's used in constant low concentrations throughout the grow.
