@DrDawg that is so impressive! This plant was a gift when I moved to start medical school so I am doing my best to keep it alive. I have ordered a grow light that should be here today, and watered it very well yesterday. This morning however, I woke up to the most mature leaf looking like this. The darker color is rather crunchy and the white areas cannot be scraped off. Any ideas for how to handle this? Should I remove this leaf? Sad because there are only 4 on the plant right now
