Bruce,

The sticky stuff is called honeydew, and it is quite common.

It most likely (most often) is harmless, or even a sign of a healthy plant.

BUT sometimes honeydew is a sign of pests, because some pests either produce
sticky stuff themselves as part of digestion process, or when they chew on
the plant more honeydew is the result, or honeydew attracts some pests
because it is sweet. So whenever you see a plant with lots of the sticky
stuff, check it carefully for any signs of pests (make sure to check under
the leaves and in crevices, and look for damage to leaves that may have been
caused by pests). If you do not find any, then the honeydew is just
harmless.

Some people prefer to wipe the honeydew off, so that it does not attract
pests, but others just leave it alone, and most of the time that's fine.

I noticed on one of my Phaleonopsis today the the flower stalk at the top
near the bud and one flower has become very sticky, like someone spilled
sugar water on it. Didn't see any bugs such as Aphids on the plant. Knowing
some plants exude sap (and still being a newbie to orchids).... Is this
unusual? it is at the very tip between a flower junction and the new bud
junction coming in on the tip?
