leaf problem

Heya konopek! Looks like you may have some critters on the undersides of your leaves. Have a look, they may appear white, green or brown. You can use neem oil to get rid of them, use an insecticidle soap or water with a drop or oil based soap. I spray the canopy, the undersides of the leaves, the stems and soil. I do this a few times a week and when I no longer see any I continue for one more week to be safe. Have a close eye, they can be really small! Cheers and goodluck
