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?)

Dont think it is frost ,A guy a couple of lottys away from me has had same ..We wondered if it was down to him using his muck underneath them a bit fresh .Anyway it has grown out on leaves above... One guy said it was down to all rain we have had ....cheers Jim
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.
