On my lowland nepenthe ampullaria, there are these tiny spots(black) on the underside and top of the leaves. A number of professionals have told me that Nepenthes don't get black spot. I don't know if the plants are supposed to have these spots or if its a disease i should take action against. The plant looks healthy and is pitchering but i noticed in on my nepenthes campanulata as well. Someone help. hehe.
