Bruce, I have the following that I bought when I started with orchids:
Grow More Premioum Orchid Food:
Bloom Formula (Blue) = 6-30-30;
All-Purpose Formula (Yellow) = 20-20-20;
Growth Formula (Red) = 30-10-10;
Urea-Free Formula (Green) = 20-10-20.
To be honest, though, once these are used up, I'm probably going to just use Miracle Grow, as I see how wonderfully your orchids do with it.
