That soil kind of resembles mud are you watering a lot? Just use some good potting soil, no nutrients either (I mean additional)... if you have been watering too much, I would let it dry out a bit. The plant looks very pale and fragile...
Yeah that looks like shitty soil. Just pickup the best potting soil you can find. I've had good luck with Black Gold from my local hardware store. And be careful not to over water. Just mist the soil a couple times a day till it starts looking healthy.
