Masdevallia "Peach Allure" question about growth habits

[AndreaK]

Question: When do Masdevallia typically start vegetative growth, before, during, or after flowering?

Information: Plant is Masdevallia "Peach Allure". I purchased it, in bloom, in January. It is potted in fine bark, in a plastic pot. It sits on a saucer, over glass stones which are submerged in water. The pot does not come in contact with the water. Current temps are 74° F day and 64° F nights. Humidity ranges from 68% to 99%. The higher humidity range is more common. I water it with RO water and fertilize weekly/weakly with urea-free fertilizer. It is currently sending up a new flower spike.
My main concern is the fact of no new vegetative growth.
