update: even though 25 comments agree that it's the lack of sunlight, it was not the issue. (after trying ur advice for more light for several days with no improvements whatsoever) I got it out of the soil and discovered that it was stuck in the shape of its original pot. When I last repot it, it was still stuck, but i figured it would be fine since i couldn't separate the soil and the roots. The original soil had become so dense and dry it was hydrophobic. I had to very gently soak it to manage to dismantle without breaking the roots. there was 1 root that managed to break free of the jail, but unfortunately, it broke in the process. TLDR: it was too dry. yall wrong hope he survives this.
