Planting the pole beans around the cuke was a mistake - maybe. The potential problem is the cuke in the middle getting starved for sun, but it really is just a potential problem and something to keep your eyes on. If the cuke grows rapidly it may hold it's own against the beans. You will have to ensure it can get to the edge and get sun. If you have ground space you could let it trail outside the container instead of having it climb the support with the beans.

I'm not a vegetable expert so my advice might be valueless, but I know for a fact that too much water in the root zone of many plants is one possible reason for yellow leaves. This might not be your issue but too much water can cause this. One way to check this is to insert a thin wooden dowel into your container and leave it there for a few hours or overnight. Make sure the dowel reaches the bottom of the container. If the dowel is damp when removed then the soil should have enough water. If the dowel is really wet then your soil in the root area might be too wet, and therefore causing yellow leaves. TYG

My Blue lakes were planted the Fri. before Easter. I needed a taller trellis since they have outgrown it! They attached to the rope trellis when they first started running. I leaned my rake against the trellis the other day and forgot to put it up. I went out 2 days later and had to unwind the beans wrapping around it! I'm going by the big box store to pick up some 2x2x8's on my way home. I'm going to use wire ties and tie them to the T-posts so that I can extend them. Might not be as pretty, but hopefully it will work. Note to self, buy longer T-posts for next year!

I am a new gardener, but I had success in growing pole beans in containers in Zone 10. The ones I had were from Burpee. I used Miracle Gro potting soil with a little bit of Vigoro 12-10-5 fertilizer (pellets) mixed in the soil. I watered almost daily and a month or so in, I added some more Vigoro, but I doubt it was needed. The things took off and I quickly discovered that my little "teepee" stick trellis was much too short to control them. I had to cut the plants down because of this trellis problem and because I had to moved my garden. I would suggest a sturdy, tall trellis. I have seen online where people use 6-foot wire rack shelves such as you see in closets across America. Kinda ugly but it would work well, as would wooden lattice. I am in Zone 10. The biggest issue I had was some rust and white flies, but the flies didn't do any damage to the bean plants, they just kind of lived there until I treated them with a dish soap/water mixture. I sprayed the rust (or whatever fungus it was) with a baking soda/water mixture that seemed to work. Overall, the plants were pretty strong. I'm about a month into Black eyed peas in containers and they're also sky rocketing (I added some inoculant to the seeds). It seems like beans and peas are good for new gardeners -- just make sure you trellis well (for non-bush varieties) and also be careful with the tendrils of the black eyes when you train them to the trellis -- they break easily.
