My Bird Nest fern has brown spots on some of the leaf edges. It is in an 8-inch pot. I water it when dry, and I fed it with Osmocote 1/2 strength just today, April 7. What causes the brown edges? Thanks

The humidity might be too low. Also, you should probably not let the soil dry out, the soil of a bird nest fern should be kept consistently moist. Brown tipped edges are also attributed to too fertilizer but that doesn't sound like what is happening here.
