white marks on Mint plant leaves

Question

There was no plant, no fertile soil in my tiny garden. I brought multi usage compost and planted different things. I have different types of mint and mint family plants. All of them have developed and are covered with white marks. I trim them from bottom, and they come out the same. I bought last week another light green one, after 3-4 days, it started having white marks on its leaves too. What can I do?

Answer 1

I would treat with a fungicide, such as Neem OIl.
