I have several Aeonium Kiwi and they are all currently green instead of yellow I have them under grow lights so I'm wondering what I'm doing wrong. They were such a pretty yellow when I first got them. I live in IL but the succulents are under grow lights The underside of the leaves also seem to have variable brown marks on them. I'm wondering if that's due to bugs. Some of the leaves looked so bad I removed most of the bad leaves and am going to repot. Thanks!
