Mexican haze

I'm not to sure what the purpling is on the buds. I dont know if that is genetics or something could be wrong. Either way they are moving along just great. I like the fact that alot of the nugs are uniform in size. They still have about 3 more weeks to finish hopefully they do dense up some more. I have 2 grow lights in this tent and the cheaper light seems to smaller and less dense nugs than the other light.
