lookin good, the bottom leaves is normal, you should remove anything that is 60 precent dead becarefull not to pull away the skin when removing use a sterile knive and leave smooth, you might want to consider taking some clones might be a little harder now but possible, it will safe you time and the short stature is something you would like from clones, the smoke will be better than the mother to, if you do take cutting from bottom branches, root for 10-14 days keep in veg another week or two then flower. the clones will be female. try to look for pre-flowers before you flower usally tell sex within the 4 week from germ flowering a plant to early sometimes can induce herm tendacies, in unstable gens. hope this helps, ....peace
