unknowingly, re-veg a couple times, screw up the light-cycle the light stress might turn it to one-bladers like my Willie Nelson clones just did ... my babies got weird, discovered my timer 'clock' was losing an hour a day, 'fooled' my lil' darlins ... new timer now, and they seem to be doing better ... I've been told the Far Eastern sativas are like this, more prone to stress, don't know how true that is ... but, a freak is a freak, I got NO place for them in my gardens :smokin:
