Hey man, as I said in pm, we've never encountered this with 1 hbss, let alone 6, and when we grow them out it's in numbers of 50 plus.
outside they can go a little longer but you would still be seeing decent flower development by 50 days.
The short phenotypes are ripe at 60-65, the mediums at 70-75, and a large sativa dominant phenotype could surpass that but they aren't common.
the seeds we produced last round were all from the best medium sized phenotypes.
I don't really know what to suggest, as we have never had a report of this occurring. We never put our strains into 12/12 to induce flowering, everything is 18/6, 20/4 or 24/0
kind regards, mitch
