Hi
I am growing my first cucumber in the greenhouse and I have started
getting some problems that I could use some help with.
The main thing is that the leaves are starting to turn yellow, it
started at the bottom and it is now working its way up the whole plant.
The second thing is leaf curl that I think is been caused by aphids this
is affecting the leaves at the top of the plant, can I spray cucumbers
to get rid of these pests.

Thanks in advance
