Estimated time to harvest from pics

Hi I was just looking for a bit of help/advice as it's my second ever grow. She's an OG kush autoflower from bakery seeds I believe (got it as a freebie, and binned packet). Problem is I didn't take note of when I planted the seeds. I would estimate she's about 8 weeks old now and the recommended life of strain is 8-10 weeks. Pretty much all of the pistils are still white though but the fan leaves have started turning yellow and dying off. The top 2 pics are as of right now and the bottom pic was on july 13th just for best context of time of how old she is. I was thinking of giving her another week of nutes, a week of water and hoping she's still alive enough in a couple weeks and ready to harvest?

A long time yet.

keep feeding , start to slow how much.

Say one week more were you are then 25% less for a week then 50% etc...
RH and temps in check . Nice work you got there

I’d estimate 3 to 4 weeks. I asked too when mine looked about like yours, and was told 4 weeks. I waited, and glad I did. I harvested yesterday and got a shit ton from one plant. The waiting until for sure done really pays off.
