1st day of flowring starts when?

I have a single female plant in small closet grow with a 150 watt hps light. I am using fox farm happy frog soil with fox farm nutes. I switched to 12/12 on 5/25 so the 20th of this month which is this saturday will be 8 weeks or 56 days. So when would I count the 1st day of flowering? The 1st day of 12/12 or a week or 2 after switching to 12/12?

the first full day of 12 12 is when the flowering period is activated.

ok thank you. I see some people say that flower starts a week or after switching to 12/12 because the plant has a growth spurt before starting to flower. So the breeder says indoors from 8 to 10 weeks. so my plant is almost done with its 8th week, so 1 or 2 more weeks she should be done?

i count from the day i go 12/12. 56-60 days later im usually chopping

Flowering begins when you first start to see flowers/pistils.....DUH!

It doesnt matter....the plant will tell u when its finished if u watch IT...not the calander
