My orchid has yellowish leaves and it gets worse :(

Hey,
My orchid has a yellowish leaves, but only in the area what was exposed on the fruit side. So maybe some gas from fruits damaged my plant leaves? What do you think? How can I help to my orchid?

Ripening fruit does give off ethylene gas and can ruin buds and blooms. It could be that the leaf is just old as it looks like one of the bottom leaves. But to be safe I would move it away from the fruit. Ripening fruit can make other fruit go ripe faster so I suppose it could 'ripen' a leaf faster too!
