I have two courgette plants, two squash and one pumpkin, all within a metre of each other, one courgette,  its main leaf keeps yellowing, I’ve removed twice. No sign of bugs, others plats all fine ?

Thanks PS will add photo later if it stops bucketing down !

Hi Jax, I had this recently and was advised to use a seaweed feed which seems to have done a lot of good.

If it's a yellow fruited variety, then some yellow leaves are normal.

Thanks both, photo now attached, it may be a yellow one (wish I was better at labelling) and will liquid feed.
