    Rings are not good. It could be a virus, but if these have spread quickly, like within a couple of days, it is more likely a bacteria. The one spot is close to the crown, and even careful surgery may not help save the plant.

    If the plant is valuable, you can cut out the infected parts and dust liberally with cinnamon powder.

    If these spots took weeks or more to develop, then it would be a virus, and the plant should be discarded.

    Thanks for the answer. The spots developed slowly. Actually I made these photos about half a year ago. Couple weeks after the photos taken these parts of the leaves died, but only those parts where the spots came up. The plant itself stopped growing leafs, and since than developed a lot of nice flowers. And just recently started to grow a new leaf. Is there chance that the plant can fully recover from virus infection and the problem never comes back?

    If the problem never comes back, it probably isn't a virus.
