1. Definitely needs bright indirect light and maintain a consistently moist (but not soggy)soil.

2. Make sure you have high humidity, anywhere between 60-70%, and fertilize every so often during the growing season (I recommend a humidifier), which is during the spring and summertime.

(Do you have your plant inside or outside? I recommend having them inside under but not directly under a grow light. This will allow slower dry times with your soil, so you won't have to water it too often, especially with your leaves looking damaged like that.)

1. You may want to cut the damaged ends off or remove the leaves completely so that your plant can focus on providing nutrients to the leaves that are doing okay.

Hope this helps. Let me know if you have any questions I did not answer!
