Yellowing plus drying vine leaves

Grape    None Given

Early summer in hot (Middle East) climate. Pot-grown grape vine with some, not many, very sad looking yellow leaves. Others brown and crisp out. Water twice a week, general plant food once a month. Overall growth ok but less strong than last year. Any thoughts please on food/water/love deficiencies ?

It looks like physiological stress and since the plant is in a pot and not exposed to field conditions, I suspect it is not an infectious disease.

It might require a large pot, there is a condition call root bound, where the roots have no space. If you take it out of the pot you might see this (as roots in a mass, near the pot). Having too little space can cause this physiological stress

Thanks David. Big job to re-pot! But probably we'll give that a go next winter.

I have the same problem in my backyard vine, but It is not growing in a pot though. I suspect root rot due to soilborne fungal pathogens
