So I have never own a succulent before, but now that my roommate decided to bring the succulents in her office because of covid, She was nice enough to gift me 3 of her succulents. The thing is I didn't knew you were not supposed to give it water everyday and one of them's leafs are getting a bit whiter. I change its place, the time I watered them, but pretty much nothing I did changed the leafs. Should I be concerned?
