Dtps. Joy Green Bee, need some advice!

[denvervet]

Hey experts! I have had this Dtps for over two years. It kinda grows but never looks all that healthy, has fantastic roots though! I would say the leaves are soft and leathery and some have a grayish tone to them. Never has bloomed and I am treating it as a phal. Its in a phal mixture with spaghum (sp?) moss, bark, cork and charcoal. Doesn't dry out as fast as I would maybe like it too. Any advice on this? It gets very bright light all day as its under a flat roof skylight which is huge, no sun. My Phals do excellent in this light and are together with this orchid.
