ok so this is my very first grow. im pretty sure it's just bagseeds but idk the plant was given to me at about a month old and im pretty sure its like 3 months old now. but i would hate for it to die at this point, especially since it is female. i really dont know to much about growing. i just water it every couple days. i know i should use fertelizer, but again this is just my first grow and am experimenting and dont know how to use fertelizer. some of the leaves have big brown spots and some are starting to shrivel....can anyone PLEASE tell me what the problem is here and what i can do to bring my baby back to life. You guys dont even know how much i would appreciate this.....here is some pics......
