search ''topping a marijuana plant''on google. ....we dont teach people how to grow weed here....usually we only answer specific questions because we took the time to read and study growing and feel that you should take the time also..... ...you have a set-up with a light and you managed to get it past 2 weeks so you must have some basic knowledge....ask a specific question and we will answer it but we are stoners...we have no desire to type out instructions when there is a million tutorials on the internet.....
