If you don’t have a growlog please answer these questions.
What strain are you growing? Is it Auto, Fem or Reg?
Are you growing Indoor or outdoor?
Are you using nutrients? Which ones? How much?
This means that your plant is totally overwatered. Additionally, a nutrient lockout is beginning.
Such a small plant in this large pot is massively oversized. On top of that, it is stretching brutally. You can counteract this by turning up the light or hanging it lower.
It would be important to know which strain, whether Fem or Auto, etc.
