This auto should be close to done by now. She is showing some deficiencies.
How did French are you watering her and how much? Do you ph your water? Is there chlorine in it?
@Wenny, I do not think it will yield much it has a lot of problems. Personally I would toss it and start over. You should learn the weight of your pot when it is dry by lifting it then learn the weight when it is watered. Feed the plant let it dry then feed it again. Your roots grow when they go searching for food.. this makes your plant grow.
@Wenny,when you first fill your pot with soil before you add any water after to it lift it with 2 hands and remember that weight. This way you will know when to water your plant.
