Update: The two from supermarkets were gone BUT... This dendrobium is still standing (or seems like it) Just wondering if anyone has any idea what's going on with it? Something's "growing" from the stems.
Hal is most likely correct. There is another possibility too though. Depending upon the parental species in the background - if it has Dendrobium nobile (and or some of the related species) in it the they may also be flower buds starting to develop. This is about the right time of year for nobile species/hybrids to initiate flower buds along their unbloomd canes (essentially this past years growth).
I haven't fertilized it yet (afraid it'll hurt the plant more after a mold problem). Is now a good time to fertilize it?
Probably not, but it's hard to say if you don't know the plants recent conditions. Dendrobiums usually need to be kept cool and dry in the winter and you resume regular watering and weekly fertilizing after flowering in the spring.
