Flowering? When the counts starts

After your switch to a 12/12 light schedule when do u start to counts the weeks of flowering the day u sjwitch or the day u see buds forming?

Me personally it starts when I make the transition to 12/12

I start when she starts to show a little bud

Worth a read

Flowering doesn’t begin with a light switch!

I usually start about 2 weeks after switch myself @Inplantsight
But @bob31 have you a good link and suggest :+1:

Thanks for the input guys

I usualy start counting 2 weeks after the switch, usualy after the stretch period is done.
