Your plant is going to die soon. Sitting in the windowsill isnt enough light. Cannabis is not a shade loving plant. If you want to actually grow it (and what is the point of doing it unless you are actually going to do it, amirite?), invest in some lighting, a small circulation fan, and temperature control means. Half-assery wont cut it here, I'm afraid. And if you are living with your parents and experimenting with a seed you found in a bag, do yourself a favor and dump it now. No sense getting your parents in trouble for something you're not really into anyway.
