I’m not sure what plant this is, the iSeek app says a kalanchoe luciae. It always been this color, not reddish when I google pics of that kalanchoe. I’ve had it 6-12 months, was fine in the beginning and slowly lost its bottom leaves and the upper ones are shriveling. I water once every 1-2 weeks, it gets pretty good sun. I’ve only fertilized it once. Planted in succulent/cactus soil. What am I doing wrong?
Thanks!
