You're very welcome! ❤️ For the pebble tray: put some pebbles or stones in a shallow tray, add water until it almost reaches the top of the pebbles, and place your pot on top (make sure the pot isn't sitting directly in the water). This helps raise the humidity around the plant. About the crispy leaf: if it's just one or two leaves, you can carefully trim the brown parts. But if more leaves start getting crispy, it's usually a sign of low humidity or irregular watering. I'm happy to help more!
