Looking at the above pictures Should I remove some...

Hey brother, looking good there! I would suggest to remove all the very lower leafs and bud site,.. in order to redirect flowering hormones towards the tops, mid section or the plants. This will ensure a larger denser yield of quality bud, as oppose to some popcorn air buds from below. Regarding defoliation... I'd ensure the stretch has fully halted... then look to remove any large fan leaves directly covering bud sites, for starts. Then work your way down the stems taking away any large fan leaves that seem to be in dark cramped conditions, or impeding bud site light penetration. Take before and after pics, you should definitely see a visible difference after your done. And have a pile of fan leaves to decompose! Of course don't go overboard...but make this defoliation practice purposeful... (allowing more light and air to reach lower mid buds)... check out a grower on here called Takeshy, refer to his gorilla zkittlez grow, he's got some pics of a before and after defoliation, to give you a visual. Hope this helps Regards Bigface
