I have had a read and am sorry to here of your plite.
Lets start with the name ,here is the correct spelling
Jiuhbao Gold = Shonan X Kaizumic Delight and both parents have s species as the pollen parent.Shonan having marshallianum and Kaizumic Delight having varicosum.
From what you have said about the roots ,it sounds like it is not dring out between watering and has lost a very large part of its root mass and can not support the flower spikes.
Another possibilitity is bud blast,or the equivilentas there dont have to be buds on the spike.I had that problen back early July when my plants were frosted.
I would sugest that you repot the plant as there is still time for the plant to develope some roots before winter.
Hope these notes are of help.
