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?
