Hello, thanks for the advices but I think this isn't the result of any movement as my Clivia is inside for a few months now and at the place where no one can hurt the leaves. I also don't water it too much and never water it inbetween the leaves (not sure how is it called in English). That black marks are on new leaves only and those leaves are unusually pale green. Thus I think there's something wrong. Not sure if I should remove those leaves (in case it's some type of fungus).
Sallyg... Great and your Clivia is blooming. It's always nice to have flowers in winter 😊. Mine blomed every 6 months until I started to have problems with the soil and little white bugs in it, then fungus in the soil aand now this 😓.
