If your 4 weeks into flowering you probably at least have 3-4 weeks left minimum, if its sativa dominant maybe longer. Your best bet is to go to radioshack and purchase a pocket microscope 60x-100x or 30x if they have one. They'll know exactly what your looking for and there only $10. Then look at the handy guide i have attached.
