Ascda. troubles

[Adela the beginner]

I have several of these orchids that i purchased as seedlings. recently i noticed that the leaves are curling and not as fanned out as they should be. i am only able water them (with mist) early in the morning. i try to soak them once a week in a bucket of water with fertilizer. All of them are hanging outside under the patio. Am i missing something?? Doing something wrong?? any advice will be appreciated. thanks.
