I’ve had this plant for years. It sits close to a window where it gets bright indirect sunlight. I bottom water it about once a week and add fertilizer to the water almost every time. It‘s in a chunky soil mix and a clear nursery pot with good drainage. A couple of month ago, I noticed the leaves along this one stem were coming in with gaping holes in the middle of them. From the looks of it, the new leaf that’s growing will also have a hole. None of the leaves on the other strands have this problem. My plant seems to be doing fine otherwise but it’s really just annoying me aesthetically. Any thoughts?
