I've been growing a butternut squash plant in a 50l pot. I water it regularly and I can see a couple of squashes begin to grow but I'm worried about the leaves. What's wrong with the leaves?0

The yellowing is most probably caused by nutrient wash out - feed the plant regularly with a tomato-type liquid feed.
If the yellowing persists and spreads to other leaves then it is probably a magnesium deficiency - in this case, add 2 tablespoons of Epsom Salts (magnesium sulphate) to a watering can and use that in your watering routine once a week until the green colour comes back.
For cucurbits grown in containers, it is very important to keep the compost constantly moist - do not allow it to dry out, especially when the plant is flowering and/or carrying fruit. The plant may abort the fruit if conditions become too dry.
If you want optimum results then feed every 3 days at a third to half strength.
