okay so i planted a seed about a month ago in a little patch of land that noone goes on. but a month ago it had just been mowed and i thought it would be easy to recognize my plant if it grew. but now the grass and everything has grown back and theres something growing about a foot or more high in the area where i planted my seed, and im not sure if its marijuana or just a regular weed. A. are there anyways to recognize a marijuana plant? B. and what should one look like after a month?
