last season I experimented with light/time sexing. After 6 weeks of 20-4 I went to 12-12 for three weeks to id sex and went back to 20-4 to return to veg. Many, many of the plants had those leaves and growth patterns right through the season. Some came around at the end, most didn't. The head was not the best compared to plants I didn't use that light/time experiment.
