Every time an orchid gets moved to a new environment it potentially goes through a period of stress - humidity change, temp. change, light change - all can have an effect. Give it some time to adapt to your place before you panic. Don't over-water. This is the most common first mistake. Some of my dends are just naturally yellowing a few leaves this time of year. Often when I repot one it soon thereafter looses a few leaves - keep the pot size down - they like to be root bound. It is going to want a fair amount of light - put it where you like to enjoy the blooms, but afterwards get it into a place where it will get morning sun or late afternoon sun. An hour or so of cold air drafts would certainly raise havoc with blooms - not sure about yellowing any leaves? More likely repotting. Good luck. mike
