I think the breeders go by from the time you see pistils...So if a breeder says 60 days flowering time, that's 60 days from when you see pistils.

Yes flowering time is the start of 12/12

Yes here's what I do because I have a perpetual grow & my bloom room is always on 12/12:
Start 12/12 light cycle, when you see white pistils emerging that is day one; mark the calendar.
Then count out 9 weeks; 63 days. This is when you should be checking trichomes for ripeness - most indicas and hybrids should finish around 65-70 days. Sativa doms are typically done a few weeks later than this

Counting from the flip seems fraught with peril. I have a Super Skunk seedling that was changed to 12/12 at the same time as the other plants. It took a full 3.5 weeks to start flowering. I've already harvested the other plants, this one is still multiple weeks behind the others. Seems like counting from seeing pre-flowers or first buds makes more sense.
Or just not counting at all and going by trichomes.

The hard part is actually being patient enough to wait for the proper time.

It should take about 7-10 days for your plants to transition to flower mode. If it takes longer than that then you did not wait until the plants were mature enough to sex to flip them. Your photoperiod plants must be at least 6 weeks old before you try to flip them or you'll get a delayed flowering response. Cannabis plants do not choose sex until the onset of maturity so I try to veg em 60 days or more in my perpetual grow but that's just me...

I count from the day i flip the lights. That way i can compare flowering time between strains.
IE. White russian pjstils show fast for me. Maybe 10 or 12 days. Meanwhile, my AK47 takes about 14 to 20 days to show pistils. Both are said to finish in 9 weeks and i found that to be true. But the white russian finishes faster by my count from the day i flip. White russian finishes for me in about 11 weeks while the ak47 finishes in about 13 really.
I think breeders try to hide that fact by counting from when pistils appear.

There were two seedlings that were both around 45-50 days old. They definitely had not shown sex. But, one showed sex and started flowering in about 15 days. While the other took a full 21-25 days to show sex and start flowering. It also ended up being about 4 times bigger than the other one.

What you are experiencing is an immature plant or plant with retarded flowering. The plant already knows that it is receiving only 12 hours of light starting from day 1 of flip, flowering hormones are already building up at that very day. Its up to you when you want to count because they could finish earlier or later.

It ended up being the strongest/best looking of the four plants. Looking forward to it finishing up.

Yup. It got to veg longer
