staghorn fern help
So, originally I was worried that my staghorn wasn't growing any new fronds...and I was told that maybe I was underwatering it. I followed the whole water it often and soak it (I just couldn't bring myself to do it 2x's a day--so it was more like every 4 days). And now its leaves are falling off! Yellowing and browning from the center. Am I overwatering it? Is this something else? It's sort of near a vent so I just moved it. But it was fine before so it makes me think it's the water. Also, the leaves are not rotting, so I don't think that's what's going on below. Sad...because I really love this plant.
