Uh hi, I need some help with my succulent. I'm a beginner type thing, and I don't necessarily know what kind it is; I was trying to look online for something similar and I think it may be a echeveria agavoides? But I'm not sure. Anyways, for a while now it's leaves, which were green when I first got it, at the tips have turned a purple redish? And now for some reason at the middle/center part of the succulent a stem started to grow out of it. I am not experienced with succulents so if anyone can help, please I need it.
