progress on KJs plant

i've had my plant know for almost over a month, the growth paterns are still similar to before where the plant looses from the bottom and gains from the top. the water has become a sort of brown yellow colour. the amount of water has also decreased since the firt day to nearly half the initial amount. the plant stands on my window sil so it gets good amount of sunlight. the leaves use to be pink in colour but most of the new shoots are green and not pink. no signs of a flower yet. the plant looks rather droopy and not healthy, this could be because of the heat its exposed to on my window sil. my plant continues to grow and loose leaves every week, the amount of leaves comming out seems to match the amount dying, so thus the plant looks rather empty from the bottom and full and lush on top.
