Today water showed up on 1 leave. I do not know what this means? Need help!

 Has this happen to anyone else?
Will it harm the cutting?

I got the cutting in Sept. it has been growing very well. The cutting came from a friend of a friend. It is a white fig that came from Lucca Italy.

Thanks Bugs

I think it is a sign of high humidity.
When I close the plastic storage box with rooted cuttings inside, I get such drops on leaves. I remove the top for a few hours to air the box when I notice such condensation and the drops evaporate with no residual damage.

The cutting is out in the open under lights. The humidity in the room is 45%. The cutting is 15" tall and it is a big leave.

I do not know if it is accurate. My window have a little sweat at the bottom in the morning when it is in the teens. When the sun comes up it goes way. I thing my house is not to dry or to humidity.

It is in the middle of the room, about 8' from the window.

Leaf rust can be a symptom of high humidity.

If it is rust what can you use to stop it from spreading ?

The leaves are removed.

Thanks for every ones help.
