hey guys!! i recently got my first plant and it’s a diffenbachia camilla (dumb cane) i believe?? this is my first time handling any kind of plant. i bought it from a shop that was by me and i have no clue what i’m doing, i’ve done a lot of research. was just coming to see if anybody could tell me if i’m doing okay so far? i’m not sure what the plant is supposed to look like and i haven’t had it for long!! i’m seeing a couple of brown spots and yellowing leaves.
