Change to Advanced nutes, get the light closer to the tops and try to keep it as low as possible without burning the tops. Put your hand under the light, if you feel heat you are to close. If you are cooling your light you can run the light closer. put in some mylar to reflect the light everywhere even cover the floor. you will be surprised how much this will help. You could also run a little longer vegging period to beef up your ladies. Lookig great though. Take care
