Hi,
I've got a couple of plants which is all I can fit in my single room accomodation. They are not looking particularly healthy. The one on the left is doing quite badly, compared to how it was looking when it was originally purchased. I'm not sure what I'm doing wrong.

I was originally watering it every day, however the plant deteriorated. I then read on the label that it needs less water in winter, and being winter at the moment, I am now only watering it once a week. The soil still feels moist, or perhaps it's just cold to the touch, I'm not sure.

I've taken some photos so hopefully someone will be able to help me.
They are available at http://xidra.com/plantie/

edit: I also gave it fertiliser a week or so ago, because it mentioned i should do that on the label. It is also around 3 months old.

Any help would be greatly appreciated.

I feel like the white specks under the leaves may be an indication of what's wrong. It is a mineral or something that the plant is trying to get rid of?

Time's running out, please help :)

Yeah i agree with khuri....they must be ants...
