Hello, can someone give me a hint here. I have two plants which are really close to each other because I did not plant those, they germinated and grown by their own as the last plant that was there was a male and looks like it left some seeds . I still don't know, but I think both are female. The plant is getting a yellow tip and now have some leaves that are getting worse. I still haven't added any type of nutrients since they are on the soil directly and I saw that yellow tips can be related to overfertilizing. Thank you!
