I need advice! So i believe i have a chichipe cactus, i noticed that one of the cacti were turning colors at the bottom as seen in pic 5. I thought it was overwatered so I was gonna cut it and try to save it, but when i got into the pot and pulled them out, all four were yellow at the bottom. The soil was as dry as dust so im assuming underwatered? I just want to be sure because the yellow seems a little bit soft but not like stem rot or root rot soft you know. They are also kind of wrinkling at the bases before you see the yellow part so I dont know! Im still a beginner and Ive googled it and it keeps coming up with underwatered or overwatered
