cause for concern?

Hi all, noticed about 15 or so leaves on my cherry with small and light black spots on both sides of leaves. container plants. none of the others nearby have issue. can anyone identify? if so what to do? im doing a weekly spray alternating with serenade, neptune's and actinovate. plants look otherwise healthy with some minor leaf upward curl. thanks all for the help!

It may be beginning of septoria, we had to much rain. It washes off all that you sprayed. Use fungicide.
Septoria usually starts on the bottom leaves. Sorry.

hi,

have you noticed any insect ( thrips ) on your plants lately by any chance?
also, it would help if you could post some more close ups of such leafs and overal infected plants photos, and check the new growth on those for any abnormalities.

also ( sorry for so many questions ), what's the stage of your plants at this moment, and if there are some well- sized fruits on the infected ones, is there anything unusual with it?

br,
ivan

p.s.

first impression suggest TSWV more than Septoria, but those photos absolutelly not sufficient for anything conclusive there.

thank you everyone. its late so hard to take pics but i am posting one pic showing the size and another pic taken earlier of a close-up of one of a leaf. i put them in pots about 3 weeks ago and they are just starting to blossom, no fruit yet.... we are expecting heavy rain tomorrow and thurs, then a sunny weekend so i guess i should wait to fungicide again. i have not noticed any thrips but will inspect tomorrow morning. new growth seems ok. these are middle leaves affected. whatever it is, is more easily seen on the back of the leaf and the spots do not have any yellow or discoloration around the black. maybe i should cut off the affected leaves?
thanks again.

The plant looks fine, but be in an alert stage, it sometime goes quickly. I would spray even if it will rain. As a prevention of a fungus. I am in NJ, I know exactly what we are dealing with. I already pulled 1 plant.

here are the latest pics. seems to be getting worse on the plant. luckily none of the other containers have this, and I have isolated this container. hasn't spread to top leaves yet and blossoms seem ok. I did a Serenade spray yesterday. would love thoughts?
PS- the cuts/creases in the leaves are just from being in my pocket

If you have magnifying glass, check for mites. Hope its them. Than it is controllable. Good luck.

Looks a lot like what's going on with one of my plants. I have a recent post as well if you want to read up on what people have been telling me. My post is "Bacterial speck, septoria or something else?" I posted pics of the worst leaves that I removed, but most of the middle leaves are affected to some extent and they vary from having just a few specks to what your pics look like. I removed the ones that looked like the pics I posted. I think it's interesting that you're also noticing it mostly on middle leaves. I barely see anything on the newest growth, maybe a speck here or there. The plant only has a couple very immature fruit and they look fine. Some of the buds have specks or look a little purple/brown around the edges of the green leafy things that go around the flowers and some of the flowers look the slightest bit brown.

Someone on another thread mentioned potassium deficiency and I just don't think that's it because I see specks more than overall purple color or veins. A few of the newest leaves have purple veins, but I have to look really hard to find them.

I hope someone can help us determine more accurately what we're dealing with. I'm hoping for something bacterial or fungal that I can keep spraying for. As weird as it sounds to say I hope for that, it's better than TSWV.

thanks. I realized its only on my cherry hybrids. all the rest are fine. i have a cousin who is an expert and he says not to worry... fingers crossed.
