Hello, I bought a small farmeri at a local orchid show and it is in spike with numerous buds. They have not grown bigger in several days, and they have all their colors and they look dry. I touched one and it just fell off. What should I do I tried spraying them because I thought humidity might be an issue.
If they have already dried up, they can't be revived. Unfortunately bud blast is common when you buy a plant and bring it home, due to different conditions.
I might be worth checking it's roots as root problems can cause bud blast. However as violetta said, it could just be due to a change in environment, that's always a risk when bring a plant home in bud.
If the buds are looking wrinkled I'm afraid it's already to late for those buds
