You need to transplant to bigger size.

Around 3 weeks your plant will be root bound if you still use the 2 liter. Root bounding will cause slower growth, less yield, potency, etc. And if you plan on letting it grow for a few months, it will start strangling its self, you will start to loose leaves real fast, and will have wasted your time.

Shovel out the money to buy at least a 3-5 gallon pot, with decent soil mix.
