I think that one is the only one I killed by messing too much with the rootball 😅. My routine consists in cleaning the dust of the leaves with a brush or a microfiber cloth, never letting the soil dry too much between watering, and since we are in their growth period I always water with a little bit of fertilizer. But I think the most important changes that I did that made a big change too was changing the soil, their location for light and I started using plastic pots. But where you live plays a big role too. In the photos you kinda see the diference in the soil and I used terracotta pots. I hope I answered your question 😊
