White Spots on Gourd Leaves

[jo9919]

I have a Gourd planted in a container. I have noticed today that two of the leaves have small white spots on them, the other leaves seem fine. The white spots seem to be on the upper side of the leaves but can be seen on the underside too, it looks as though they have started on the top but gone through to the underside.

Does anyone have any idea what has caused this? Will the plant itself be OK or should I dispose of it?

Jo.
