New to planting and I sucks at keeping plants alive. I've had this Rabbit's foot fern for about 3 weeks and it's been doing great except now I'm starting to notice that it's going brown around the edges? It's in a 24" tall viv, direct-semi indirect sunlight, and soil humidity is fairly high as it sits right below mistking nozzle. ABG substrate. It seems like it's slowly going downhill. Anyone know what I'm doing wrong here? Sorry for the google drive link but my free photobucket is already full and cant figure out for the life of me how to upload photos.
