When do you start counting flowering with autos

[Smallgrow]

For the auto pros out there.
At what point of the plants growth do you start counting flower weeks?
Since we don’t flip light schedules I’m not really sure.

I don't know about when, exactly flowering starts, but I start adding flowering nutes to veg at 4 weeks and am 100% flowering nutes at 5 weeks.
The reason is only because grow time has been about 10 weeks and I'm shooting for the middle as if I were flipping fem when I did 8 weeks veg and 8 weeks flowering.

Watch your plants and they will tell you. I start the transition to flower nutes when I see the autos start showing signs of flowering.

Same here, as soon as I see preflowers she's in flower.

When you see white pistols at your nodes start giving flower nutes. Autos need more nitrogen the first few weeks of flower than photos do.

I went with pistols too but started the transition to bloom nutes just a bit earlier because of high N.
