Hi there, iāve had my pothos for about 2 years now and itās been growing great but i was just cleaning the leaves and i noticed this! i dont know what it is, i didnt see any bugs or anything, is it mold? how do i treat it? the plant hasnāt changed much other than a few yellow leaves but i figured it was due to the weather changing. do i change the soil? do i move the plant? i will add its in my kitchen and it is more humid in there. please help a plant girl out šš„ŗ my pothos is my prizeš©¶
