Can you tell us what you did that was abnormal of your care with her? I fucked up & killed one of my ladys by placing Milar under her in early july within two hours of me placing it under her to reflect light. Mistakes where made. Did you feed her somthing new?
she does look a little damaged, but it looks like she healed on the splits.
her stem still looks alive but im no doctor.
Maybe she took the nutes from her leaves to fix the splits?
Plants do that kinda stuff.
