Leaf Soak Spots? Please help!

[RosieC]

It looks like cold damage to me as well.

While cold damage will not spread as such (of course more cold can make them worse) Rob is right that infection can get into the spots and that can then spread.

I would keep a close eye on them, any sign of something spreading out from the spots I would remove the affected leaf.

It might be worth using something like cinnamon on the affected spots to try and stop an infection getting in.
