Looking really good there. I have recently learned the key to growing a big Lowryder and your grow confirms it because your plants look great and finally so do mine. The key is keeping the light high enough above the plant that it is not bleached and stunted. All my girls have turned out to be 12 inch midgets and I tried everything and finally found the answer was that I had my 250 Watt HPS too close to the canopy. It's not nutes or pH or temp. I had my lights to close. Moved em up about 5 inches and my plants are monsters compared to previous grows! I see your light is well above the canopy and your plants look bushy Healthy and big. I read thread after thread of douchebag advice about keeping the light as close as possible to the canopy, but I bet none of those guys ever grew a dwarf strain!
