Cucumber Plants Dying

I have six cucumber plants, 2 in a small greenhouse and 4 in a larger greenhouse where I’ve taken most of the glass out of the roof and replaced with chicken wire to keep the squirrels out.  Obviously this one does not get as hot.
Ive now lost one plant in each greenhouse and the others are starting to deteriorate.  So I think this rules out temperature, humidity etc as the cause.
They are planted in ring culture pots and are watered and fed regularly.
The plants just seem to have stopped growing and some have pale spots on the leaves like it has dried out. There is no powdery deposits so I don’t think it’s mildew.
any suggestions please?

    We have 2 cucumbers planted in the gorund in a polytunnel. They have been producing arm length cues for some weeks now and are up to the roof and growing sideways.
    It does look as though your plants are suffering from too small a space and maybe lack of water.
    Can you plant them in the ground?

    I'm growing cucumbers for the first time and was told that you needed a really bit pot if growing in a container.  I'm no expert at all but the size of the pot could be a reason.  More knowledgeable people on here will be able to advise though.

    I use a 22L pot for 1 plant in my greenhouse and the pot is filled with roots by the end of the season.
    They are also hungry plants and I feed mine weekly with Miracle Grow.
    You need to pick the fruits soon as they are ripe otherwise the plant will stop producing more fruits. The more you pick, the more that grow.

    I have a similar problem but can see there are some new growth and some fruit appearing.  I have cut back my leaves and as they are in a bed rather than the ground have put some more soil but also watering them more at the roots to see if they will pick up.

    Thanks. Too small a pot makes sense

    A rich compost in the pot too helps a lot.
    I had the best results using 50% rotted farmyard manure and 50% MPC

    You mentioned ring pot culture so I presume those are bottomless pots. What is beneath them for the roots to grow into? Is it decent soil with a gravel mulch?

    No the ring culture pots are just standing on about 3 inches of gravel. I did put some mushroom compost in the bottom of the ring culture on top of the gravel
