Issue with potato plants? [With photos]

[LewaK]

Hi all! I hate to post two threads in a day (or two days) but I have only just noticed these issues and I'm concerned now

The above shows some 'slits'/cracks in the leaves of a not quite mature potato plant. These holes/slits were in a few of the larger leaves. Didn't look like nibbling, and is unlikely to be as these plants (and the one shown below) has been grown in a lean-to, with regular watering and reasonable (15-21C) temperatures.

The above is on the largest of the first, most mature batch of potato plants also in a growbag. Grown in the same conditions above but does not have cracks/slits, merely this weird dimpling effect. The effect isn't present (as far as I can tell) in the second, less mature plants above.

Is this my poor care letting these plants get eaten/rotten/overwatered?

Thankyou!

Sorry for bumping this but I'm a bit concerned. The variety of the potatoes is Arran Pilot, and the effect has spread to other leaves. Is this normal? The splits haven't occurred on the more 'knobbly' plant.

No idea what the second one is and the first links not working. Sorry

I'm a novice with potatoes LewaK, so can't help you (although I don't think they look too bad really). Someone with more experience will be along soon to give you some advice I'm sure.

The leaf with the split looks otherwise healthy. Not a great pic for the second problem. Could just be a reaction to the fertiliser in the growbag but it could equally be a sign of virus or disease. Again, I wouldn't be too worried. You seem a bit concerned you may have over watered. Tatties do best on the dry side of moist. When there isn't much leaf growth, they won't use much water and won't need watering.

I have no idea but I wouldn't worry too much. It's pretty rare that something disastrous happens. If you don't find any answers just carry on regardless and hope for the best. Chances are it will be fine

The first looks like physical damage. It just looks like the leaf has got folded somehow. I don't think it's a real problem.
