Phalaenopsis spike growths...

[DenSeif]

I have a Phalenposis - Sin-Yuan Golden Beauty. Has bloomed beautifully. I have re-potted and new root growth seems to be doing O.K.

Plant has two spikes that were cut back, now it's growing new leaves quite actively out of both spikes. Original plant leaves seem to be dying off..could it be all the energy is going to the new additions?

I assumed the new growths wopuld also sprout roots, but none have appeared. Should I cut the two spikes just below the leaves and re-pot? Not sure what to do at this time.

Help...
