All nutes are measured according to a standard called NPK, which stands for:
Nitrogen, Phosphorous, Potassium (k).
The bottle will be marked with something like N (7), P (1), K (5).
That tells you its proportionally high in the first and last.

During the veg. stage, where you are now, you need high N.
During the flowering stage you need to switch to a low N and high P.

Also, your soil looks pretty bad...re-pot.

Thats a girl btw, so you should put a little effort into her...
