Did you feed this plant anything? Is the medium ever dry or at least not soaking wet? What is it growing in? Water - tap or RO? Any light hovering over it?

maybe soil is too wet.

Let it dry some between waterings. Check your tap water report for PPM and for pH. Those saying tap water is perfectly fine without knowing this are often off base. My tap water runs a PPM of 800+ and kills everything but weeds after a while. Even with the pH adjusted.
