Still new to plant parenting! My variegated monstera standleyana has one lower leaf that turned yellow over the weekend. For the past few weeks it has been showing new growth like crazy considering it was propagating in water just a couple months ago. I came into work today and now the edge of the yellow leaf is browning but the little leaf on the left just popped out today. This pot doesn’t have a drainage hole so I know that is an immediate issue but it’s just weird that everything but that one leaf is doing great. Any ideas or recommendations?
