My Alocasia is browning/yellowing on the tips of its leaves. The one pictured has gotten worse since I got it about two weeks ago. Now the other smaller leaf is starting to brown also. I use distilled water to water it. I’ve only watered it once because the soil was pretty damp when I got it. It’s under a grow lamp as I live in Ohio and it’s winter. I also keep the humidifier next to it running at most times. Humidity averages about 55-60%. Any thoughts/recommendations are much appreciated!
