Is their anyway to possibly tell how old a plant is? Ive been given one, but im not sure. Its not growing at full speed anymore is all i can say.
How big is the plant, Is it showing pre-flowers, What size pot is it in and are the branches alternating. Why cant you just ask the person who gave it to ya lol, Nobody but the grower will know exacty how old it is
If possible, post a picture. Even a low quality one. If not possible, just give a detailed run down of what the plant looks like. Size, bushyness...etc.
