And another Squash Question

[chriszog]

Once germinated and producing true leaves they are starting to go very yellow at the edges which is moving inward. Has anyone any ideas as to reason and cure.
They are in an unheated greenhouse.
Many Thanks in anticipation

mine are doing that too, but I'm afraid I have no reason why either, or a cure. I wondered whether it might be something to do with watering or nutrients.  Mine are growing in loo rolls, and are being hardened off outside during the day.

over watering?

my seed leaves have started to do the same thing - but i figured it doesnt matter as they all already have several true leaves which look fine.

that is happening to my cucumber seed leaves but the true leaves are fine
