I have about 20 plants that look like this in my back yard,i have grown before but i never seen em like this,im not even sure if these plants are cannabis,but the leaf formation is exactly alike.i threw a bunch of seeds like 3-4 months ago now these things are everywhere,even in the neighboring yards.I have searched for hours looking to find a plant that resembles cannabis but none seemed to match,I have a theory that my seeds mutated into a NEW plant with cannabis genes.And all the answers i have gotten from here is maybe light,too much nutes.....etc but nature did this so.....ANYONE CARE TO EXPLAIN!!!
