What's causing the discoloration in my bird nest fern's leaves?
Lately, I've noticed that the leaves of my bird nest fern are developing some discoloration, which is concerning. I’ve been closely monitoring its watering schedule, and I’ve tried to maintain consistent humidity levels, but the leaves are turning yellow and starting to lose their vibrant green. My garden setup has a dedicated watering routine, and I’m careful not to over-water. Could this be a sign of nutrient deficiency, or perhaps an indication of a pest problem? If anyone has insights into diagnosing these kinds of issues in bird nest ferns, I would really appreciate your guidance!
