I bought this lovely Echeveria Lilancia from my local grocery store and I've had it for about a week now. It was doing really well but I noticed a wrinkled leaf in the center of the plant! I haven't watered it at all yet! I'm guessing it's rootrot because that's what I've read from a lot of wrinkled center Leaf posts on the internet. But I'm HOPING that thevplant is just thirsty! I gave it some water and am now waiting! What do you think??
