Phals don't like direct sunlight, unless it's very weak, early morning light, Cheryl. Be careful also because a sudden change of light conditions can blast the blooms. Move it slowly towards a window, but don't let the direct sun hit it.
Sometimes even good drainage isn't enough - the roots need to actually dry out between watering and big holes rather than slits in the sides of the pot are better for air movement to the roots.
