I work in a windowless office. My wife got me a plant to spruce up the place, it's supposed to be watered once a fortnight and need very little light.
It sat in the dark in the weekend and when I got it it had these water drops on many of its leaves. What's up?
I don't think so.
If you know the species of the plant you might look up what to look for in terms of under/over-watering.
But "morning dew" is something you'll see on plants all the time in nature. That's when the cold air during the night causes water to bead up on their leaves. It'll disappear as it falls off and starts evaporating again with warmer temperatures.
