She sarting look little bit better, maybe it was just some underwatering and too light nutrients.
Day 45: 1.5l water, 5ml S&R organics
Day 49: 2l water
So since this was on 12/ 12. I take it it is a photoperiod FF or regular seeds feminized. Is there even a light from a power strip or light controller or any possible light leaks? Did temps EVER get below 70 f ? Did it ever get an over done " dry back"? Leaves look dark for end flower. Was there to much nitrogen still in soil? Just a few of many ways to get a herm.
@Growyourhi, many times under 70 and soil dried too much few times, no light leaks. They are mostly purple leafs soil is out of nutrients. Only this strain/pheno hermed so it just was most sensitive for that. :)
