Here's the scoop on this . I crossed Afghanni female with Big Bud male just to see what the results would be . When I first germinated the seeds , I had problems with the root staying in the seed and the first leaves popping out of the seed covers. After many attempts I finally coaxed 30 to sprout normally . All was well untill yesterday when I noticed that there were 2 plants in full blown male flowering . Under closer scrutinizing I found three females that appeared to be in advanced preflower stage. I wouldn't think much of this except that the light cycle is 19 hours of light and 5 of dark. They are only 4 weeks old. I was hopeing to give them another 3 weeks of veg before going 12 / 12 but seeing as how some decided to start flowering on there own, should I just switch to 12 / 12 or should I just let them do their own thing ? They are between 12 and 16 inches tall and planted in 1 gallon pots.
