looks like it's REALLY over watered, can't really tell from the pics if it has spots or not on the leaves, could be a ph prob too, but all I really see is over watered, just water when the first 3 inches of soil on top is dry, or if the pot is light, this will take practice, but lift the pot when you water it, then lift it when it's dry, see the diff and remember it so you can tell next time when to water, or by a moister meter can get one at almost any hydro store for less than $20 and usually has 3 settings on it, ph, moisture and something else...................
