Fertilizers can definately stain orchid petals. For that reason I don't fertilize the plants while they're in bloom. When I fertilize I remove all the blooming orchids to another area so the spray won't stain them. I have used both powder and liquid fertilizers and I mix them with water. The only kind of dry fertilize that you should put directly in the orchid pot would be time release fertilizers. Dynomite from Home Depot is the most commonly used. Don't use dry plant fertilizer that is meant to be spread on the grown around plants grown in soil. That kind of fertilizer is not recommended for use with orchids.
