Cucumbers with watery edged leaves

[Lucilu]

Hi, I have noticed today that my greenhouse cucumbers are developing a watery edge round some of the bottom leaves. Any ideas what might be causing it?

Any kind of discolouration a pic would be good.

Hi and welcome.
Maybe its the oldest leaves dying off?

Hi and welcome to the vine.

By watery edges, do you mean this:



This is called guttation and occurs when the plant takes up water at night when the stomata (used for "breathing" out water) are closed. It is quite normal and nothing to worry about.

Thanks for the replies. I'm struggling to get my iPad to upload pics to the thread unfortunately but will have a go from my desktop tomorrow.
The plants definitely don't look healthy...droopy leaves with a yellow tinge. I fed them a few days ago so I'm thinking I might have accidentally used too concentrated a solution without realising it. Hope not as they were doing so well!
