Hi LilyB! Welcome to the forum. From your photo it is clear to me that your plant needs more sunlight. It is so dark green. Most phals do well when their leaves are a bright yellow-green. There are some darker leafed phals, and yours could be one of those, but my guess is that it is from insufficient light. Darker leafed phals sometimes start to turn red when they get too much sunlight. My guess is that you need to give this orchid a bit more light and water only once a week.

Cheers,
BD
