Potato - Yellowing leaves

[Pete the Plot]

Me again :-[

My tatties seem healthy enought but some leaves have started to yellow a bit at tips. No other visible damage. Ground quite dry. Couple of clear nights this week - Dundee (ground frost?)

could be a bit of deficiency, yellowing between the veins, but  ???

I have tip yellowing of many plants, across  different families, I have just put it down to the wet ground. But veins could indicate a deficiency of some nature.
