Dendrobium cuthbertsonii hybrids and leaf falljng

[clintonsparsons]

The plants I ordered looked great when I got them 3-4 weeks ago. I mounted them with some live sphagnum and ever since I received them they have done nothing but drop leaves. I water once per day with RO water only. I havnt fertilized yet. I completely soak the moss pad when I water and by the next morning the moss pad has dried some, but it's still moist. . The moisture level before watering is similar to a well wrung-out kitchen sponge . Humidity is 85-90 %. Nights are 48-53, days never above 75. Air flow is more than sufficient, as is light.

Is it just shock from being mounted? The canes are firm. Am I just being impatient? I am new to orchids. Also, when I say I saturate the moss pad, I meann like three sprays fr ok m a mister bottle is enough to saturate it.
