Hi there! My first fern, a white rabbits foot, is not doing so hot. Watered weekly, nursery pot, fertilized with super diluted liquid 1x/month or so, next to a window but mounted on the ceiling and his leaves are droopy, crunchy and falling off. I’m worried I over fertilized, because there’s no way he’s under-watered…but the fertilizer was super diluted too. Would love your thoughts!
