should I leave it for a couple days and see if its a marijuana plant or should I just kill it also if its Arjan Haze 3 (sativa dominant) how can I move it to the middle without killing it?
Leave the plant where it is right now. When the plant is big enough to transplant you can center it in the next pot. The root system is EXTREMELY fragile at this stage
that doesn't look like a marijuana plant...looks way too small...but its not going to hurt anything to leave it for a few days to see what it does...where'd you get the soil from?
