Dendrobium

I repotted this Den in 6-07. The potting mix is my own mix of med. fir bark, med. coconut husk, vermiculite, and charcole. It did well, put out new roots then rested for the winter. In early spring, it put out a couple of new leaves then threw a Keiki and a spike. Sounds good uh. A few weeks later some leaves dropped & the spike dried up. The keiki did well and I cut it off and put it in a small pot. The keiki is doing very well. The mother plant has failed to thrive. It didn't throw out any more new leaves, and no new spikes. It almost looks as though it is winter mode. At the present time it gets watered once a week, fertilized every 2 weeks. During the winter it got watered every two week with no fert until spring. Until last week the fert was 20-10-10, Now its 20-20-20. It gets strong filtered light most of the day. I checked the roots and they look white and healthy.The canes are strong, not mushy. I haven't had real good luck with dens and now I am curious as to what I am doing wrong. Maybe the old adage "Patience Grasshopper" will apply.
thanks

I don't have an answer but I have the same problem with a Den. dropping leaves while making spikes. Hope someone comes a long to help us.
