Oh, boy. I was using just a simple, ordinary nursery-brand MSU-type (at least, I think it was MSU type) + Superthrive, and a monthly dose of seaweed emulsion...until a lecture at our orchid society. We had a major cattleya grower come talk to us, and he shared his current fertilizing regimen...which I, of course, copied down..
His recipe was, of course, for a large batch & included things I did not have access to, but I scaled things down & added to my fertilizer/SuperThrive/Seaweed mix: yeast, horticultural molasses & sugar.
Sounds like I am baking cookies, doesn't it?
