I've been using GH 3 part for about a year now and really like it. Here are the proportions I am giving out.

Vegging and clones : 400 to 650 PPM
equal parts of Grow, Bloom and Micro

For flowering : 750 to 1200 PPM
2 parts Grow, 3 parts Bloom, and 3 parts Micro

I would be interested to know how you proportion yours out....
