Generally I expected these plants to take 8 weeks to flower. But I have had them on 13 to 13.5 hours of dark daily. Only reason is this is the only schedule I could work out with the other three plants I still have in veg. I think since the plants had a little more than 12 hours of dark right from the start they are flowering and finishing a little sooner. As I said, im right only a few days over 4 weeks and the plants have quite a lot of orange pistols. Seems the larger top buds are the ones that are orange, the immature ones on the middle and bottom are still all white. I suspect at about 6 weeks the top will be 75%+ orange and the bottom 50%. OH so sexy! White Widow, some sticky icky!
