[Pensacola Eric]

I bought a Dendrobium Burana Fancy X Thaichong Gold about 9 months ago that had a keiki with roots on it. I put the keiki in it's own pot with small coconut husk chips and watered accordingly. It was doing well outside on my enclosed patio with my other orchids. Well when winter hits here in Pensacola and temperatures drop to near freezing, I bring my orchids inside. I have a humidifier (with humidistat) in the room where I keep my orchids and there are near a south window. All of my orchids adapt well to this change except for this keiki. All of the little leaves have fallen off leaving only the two very small canes. The roots seem to be doing fine as they have taken hold to the coconut husk chips (it took a while for this to happen). The large plant has not lost any leaves and is actually just finishing blooming. I do know that some dens lose their leaves (I have one that is only canes right now). Should I be concerned with the keiki and if so what should I do. I understand keiki growing takes patience but I don't want to lose my baby. Thanks.
