Hi all! This is my elephant plant. She has lost three leaves since I bought her one week ago. The leaves quickly turned yellow, so I removed them. I am not sure if this is normal because she is just adapting to her new environment or if she is on her way out already :( She has three large leaves, which all look like the one pictured. Does anyone know if this is a normal colour for the leaves or if this may be about to turn yellow too? If so, what is most likely causing this? I have just bought a grow light but have no idea how to use it. Any advice would be appreciated, thank you!
