My first plants

These are my first plants... they are about 2' tall..im thinking about pulling the smallest one.. its getting purple and growing good.. but it has a wierd smell to it like its sour...(FIRST PIC). I was just wondering what i could do to help these plants.. they are about 5-6 weeks into flowering

5-6 weeks into flower.. not much you can do now...

congrats on completeing a FIRST GROW!!! you are on your way!!
