Yellow spots on my cactus :( I found these yellow spots all over my cactus! I have 4 of them outside… and all of them have it. I water them every 2 weeks or so. It gets full sunlight about 6 hours daily, I believe. I would need your help treating this please. Thank you! Originally by u/Coffee1194 on Reddit: https://tinyurl.com/23nvwnp6
