i have two plants that in concerned about.
the first one is a split leaf philodendron. it doesn't have splits yet because it's a young one, but on one of the leaves it's turning dark brown or black from the side. it looks kind of bordered by some yellow as well. what's wrong with it? (there's pictures)
the other plant is a pilea peperomia, and it looks health except for one stalk. it's kind of mushy and it's floppy. it doesn't make sense because the other stalks are perfectly fine. any thoughts?
