please help me to save my rose - Discolored leaves
Yesterday I bought two rose plants from a nursery. When I selected the plants, it seemed to be ok. Today I saw some difference in some leaves. Please help me identify what it is and how to treat that. Yesterday I sprayed the plants with neem oil spray(Parker's neem oil) which I usually do for my other plants. Please help me. Thanks in advance.

It does not look like a leaf miner to me. In fact first I thought that way, but it is not making a distinct path, its just a patch. Moreover it don't look like pests are eating from inside. I don't see any bugs also. I don't know if I am missing something. I want to do something to save my plant. But I don't know what to do. I don't want to kill it.

With little research I thought it could be chemical burn, since I sprayed the neem oil with dishwashing detergent. Ofcourse the ratio is fine. But usually I put the detergent first shake the bottle and then the neem oil, shake it again, spray it on my money plant(pothos) first, after that to all my other plants. But this time after mixing I sprayed it on my red rose bush which is badly hit(because of whatever it is)
I tried to remove the infected leaves to see if it spreads again. Some more googling tells me that it could be downy mildew. As the picture is somewhat similar to mine. Let see how it goes.

I think the last picture looks similar to my plant.
Thanks rainbow gardener, let me see if, it spreads then I try to take it back.
Advices are welcome. Thanks in advance.

if it is in fact a detergent, and not just a careless reference to soap, stop using detergents on plants.
detergents are not soaps, they can have all kinds of chemicals that will harm-to-kill plants.
frankly, the leaf damage looks like plain ole sun scald. if the plant was under roof and you planted it out in full sun.... plants do get sunburn.....
it is not leaf miners and it is not mildew.

You should check - most often dishwashing liquid IS detergent, not soap.
I have no idea what varieties your roses are. Where you bought them should know. Alternatively, everyrose.com
https://www.everyrose.com/everyrose/sitemap.lasso
is a searchable database of rose varieties. You can input everything you know about the rose - color, size, fragrance, rose type, etc and it will give you names of all the varieties that fit those criteria, with thumbnail images and link to more info.
For e.g. I gave it criteria hybrid tea rose, red colored, dark red ARA standard color, no fragrance and it came up with 36 varieties that fit that description. Or you can use the "browse for a rose" feature to browse through, for e.g., all the 428 dark red rose varieties.

Thanks a lot rainbow gardener. Now I suspect the culprit is roseslug.

But I am trying to find out the larvae or the bug.
