Spots on potato?
Do any of you guys know what are causing these spots on my potato-plants? 2 month old plants. The spots have just emerged during the past week.
I got the same spots last year after the same amount of time, and harvested a couple of weeks after. The potatoes themself were all fine.. (Last year was very wet, a little better growing-conditions this year).
Or is this just the way they wither? My dad thought it were potato blight, but were surprised it hadn't affected the potatoes themself.

So it could be two things. One is leaf spot disease where fungal spores float onto the leaves and make tiny colonies. These are usually not lethal but also not fun! Any fungicide should get those off. The other thing I’m wondering is if you spray your plant leaves during the day. I know that water droplets can burn during the daytime on a plant due to magnification.
disregard that, I didn't see the whole plant. It looks like the top leaves may be experiencing the brunt of this, is that correct? If that's the case, it's probably sunburn. Try moving it to a less sunny area and let us know if it's still spreading. If it is, it may be a disease and the branches with the spots should be cut
@SesameSeeds777 thank you for answering. This is only one of the plants, they are placed in couples a little away from each other to see (after last year) if they got the spots again. Some of them gets rain, some are just watered by hand at the base (so no water on the leaves).
But all of them have spots more or less now. One plant is way more affected than the one that stands next to it, that have almost none.
The affected leaves seems really random. On one plant it is the top leaves and nothing on the bottom, on another there are leaves here and there with no system at all. Some leaves are fine but most do have some spots now. It does not look like it should be the sun causing it.
I was kind of hoping it wasn't blight cause I understand there is really no getting rid of it.. It is too early to cut them down now😭

Hi @GnarlyJacaranda! Thank you for answering.
I didn't think the sun could do this as the spots are really random, also on lower leaves on some of the plants and on what I would say is the shade side. And several of them is also standing under roof so I didn't think they would get wet on their leaves (no I don't spray them). But it has been heavy raining some days so guess it might have splashed some..
The plants does look otherwise healty, just these spots that suddenly appeared. I might have to look for a good fungicide.. or maybe you have any recommendations for a hommade one?
