Question: Why is that leaf turning brown? Context: Browning leaf is the only sign of distress. No sign of pests. Watering and liquid fertilizing happens as often as the app suggests — or I snooze the task if the soil’s still wet. I used to have the plant on a shelf a few feet away from the window, where it started to droop and a few leaves died. It’s been much happier (and put out a new leaf) ever since I moved it to the sill. *I have not checked the roots recently. Maybe that’s the next move.
