Hi there
I bought a

about 2 1/2 weeks a ago but since transportation and placing it in my room the leaves startet cracking. The plant gets a lot of sunlight and is put close to the windows of an old building (im not quite sure if it is the lacking air that starts the cracking because it doesn't seem like a lot but maybe it's already enough¿). I water it once a week.
Does someone have any tips? I was planning to own it for a long time but as for now it seems like its going downhill...

Thanks in advance
