those things look pretty stretched out.. otherwise they look great. And I dont know what evry1 is telling you but if you plants are in a pot and the lower leaves are yellowing and dying off it could be because the roots dont have enough room to grow. Lower leaves dying off ISNT a good thing.. not in VEG.. it's going to make its way up the plant if you dont figure out whats wrong. You might have to transplant if the lower leaves are yellowing and you think its not a nutrient problem. Also dont bother trying to force flower.. why rush it.. just let the good sunlight and nature do its thing.. its patience.
