Hi all. This morning when I checked my seedlings I noticed that my cucumbers have a thin white edge on the seed leaves. They are about 3" tall and have two large seed leaves one similar size true leaf and one small true leaf just showing. I am wondering if this is normal or am I over/under watering?
This is the first time I have grown cucumbers, they are currently living in my east facing conservatory and have plenty of light, I keep the compost damp (not soggy) and put a plastic cloche over at night to keep them warm (I forgot one evening and the next day they were a bit floppy but have been ok since).
The white edge isn't shrivelled or dry, no bugs and the other leaves are dark green and healthy. I'd love to hear any tips for a cucumber newbie, thanks.
