I won an orchid in a draw at the local orchid club. The plant has a spike with a flower and some buds remaining on the spike. All seems to me to indicate the plant is heathy but while watering it today I noticed on 2 of the leaves something I have never seen. Under the leaves there seems to be crystals of dew, like sugar candy, a tad sticky and mostly clear. Is that dew or sap or some kind of pests way of invading a plant?
