Aerangis luteo alba var. rhodosticta

Bought these two and I wanted some feedback on the growing conditions.

They're on a rack, receiving about 50-100 FC of light. This seems low, but maybe my meter is off -- it's enough to get phals blooming on the rack below. The rack is also near a window that gets light in the morning. There is a misting system (mostly to keep up the humidity), that goes off every 3 hours for 20 secs, with RO/DI water. The leaves and exposed roots dry completely between mistings. Fertilizing 1x per week with First Rays' (12-1-1-10Ca-3Mg) formula.
