I'm doing my best to keep to the legendary GH 3-part +CalMag system above, but it would really help if someone could translate the instructions a bit further into newb-friendly mixing directions. Maybe I'm dumb, but I have trouble figuring out exactly how to mix this plant juice from that post.

I'm one week from first harvest, and pretty happy w/ the results so far, but it would be nice if I felt like I truly understood how to mix this stuff.
