Time to harvest?

First time grower, and I just wondering what you guys think. There are sooo many mixed messages online about when's the best time to harvest auto flowers.
The strain is 4 got 10
ItView attachment 4419664 will be 9 weeks on Friday.
I did though stop feeding them a week ago as I think they are pretty close.

Thanks

honestly id leave another couple of weeks,theyve still to swell and alot of white pistols still.I would also give them a feeding again,but also never done autos but shouldnt be that much difference when done.
