What are these black rings on my plants My sister got these plants a while ago and doesnt remember the name. I’m taking care of them now and I’ve noticed these patterns on only 1 of them. Does anyone know what it is and if it’s normal? Thank you I water them once a day and they are under sunlight all day If anyone has tips please help me out I’m really trying to take care of them I’m new and they’ve made so much progress since I started taking care of them myself especially after the winter Originally by u/Perfect_Choice7880 on Reddit: https://tinyurl.com/27artw9t
