How long left?

Hi Guys, hoping to get some advise on when to crop and leaf condition on my 3 babies. I’m got Sensi skunk, auto flower, outdoor strain, they have been outside during the hot spell and for the last 3 weeks I’ve put them in a grow tent under a 315w CDM with a 4” air control kit on its lowest setting. Using Snoop Dogg’s full range of Nutes and using soil as a medium. They have been flowering for the last 7-8 weeks, some of the fan leaves started to discolour about 5 weeks ago, but over the last 2 weeks they have got worse and some have completely dried out. I think this is due to low humidity in the tent but I’ve had to keep the air control going to remove smell. I’ve attached photos of them, one plants top cola is about 60% brown pistils, but the lower and side pistils only are about 20%. The other 2 plants have about 20% brown pistils. Would really appriciate any advise on when to crop and if the fan leaves are a problem that needs to be addressed?
Cheers

Another two weeks maybe .

Check the trichomes

Hi, thanks for reply and video on curing, very helpful. Do you think the Fan leaves are of any concern?

If their totall yellow and crunchy, ready to fall off..... Just pluck them off

Their in the way and dont have any food left. And they offer a home for bugs and mold to move in on .

But yeah everythings looking great pal, on schedule. Dont change a thing.

Wait another twoish weeks and watch the trichs all over the plant , not just in one spot

Thanks matey, will definitely take your advice
