A few months ago, I started nursing this houseplant. I was bringing it back to life. It was great! It healed and was lively. I had this plant in the kitchen window, which gave very little sunlight. It molded 3 times and I replanted it 3 times. On the 3rd time, I moved this plant to my bedroom. I placed it in front of the window and every morning before the sun comes up, I open the shade for it. It gets a tremendous amount of sunlight! It's been in my room for almost 3 weeks. The mold has stopped. The are growing new leaves and are reaching out for the sun. They are blooming (in December!). They looked happy which made me happy. Now, this week, I am so saddened. It is starting to die! I don't know what I'm doing wrong at all! I water it when it dries out. I never over water (there's never any water in the tray). I am using filtered water from the fridge because the ph level is perfect. I use a spray bottle to spray the plants...
What's wrong with it? What can I do? I love it. (also, maybe it'd help if I actually knew what this plant is called). Also, I don't use any fertilizers or nutrients... last time I did that and it started turning black.
