Pale leaves on my cucumbers

in Fruit & veg
The leaves have been looking quite a pale green for the last few weeks. They are in a greenhouse and I tend to water every other day or two. I am currently feeding them weekly with tomorite and last week decided to give them some seaweed feed to see if it would help.
They are producing cucumbers, had a few so far. Is this likely to be a nutrient deficiency? Or any ideas on cause ..

    The leaves look ok. They could be a bit darker though.
    I use ordinary Miracle Grow for my cucumber not Tomorite
    MG has an NPK of 24-8-16 and Tomorite 4-3-8.
    So the N (nitrogen) value for MG (24) is much higher than tomorite (4) and it's the nitrogen that will most benefit the leaves; and as cucumbers have big leaves they need quite a bit of it.
    It's healthily looking plant so you could switch to MG and see if that helps.

    Knowledge is knowing that a tomato is a fruit.
    Wisdom is not putting it in a fruit salad.

    Thanks, I think I will try some of that miracle grow. Is it the all-purpose one?

    yes - that's the stuff.
    I feed mine once a week.
    Also good for courgettes and other squashes.
    Works a treat

    I forgot to ask, is it the liquid feed?

    No, the granular feed is what I use - it's much cheaper and 1 tub lasts many years
    I use it on other plants too

    Update: I have been feeding the cucumber plant miracle grow all-purpose for a couple of weeks and the leaves have returned to a healthy darker green again. Its seems they must of been lacking nitrogen. Thanks very much for the recommendation!
