pics- Wondering if my C4 matic is ready to harvest

hey guys i have an autoflower plant called C4 Matic. its been almost 10 weeks now since it sprouted.
i had it originally growing under cfls at night and out in the sun during the day, up until about 4 weeks ago when dad said he had enough of the smell in my room lol so i had to leave it outside only.

so basically a week after flower its been just an outdoor plant. i stopped feeding it nutes 7 days ago and it seems like it started yellowing yesterday.

im wondering if you guys think its ready to harvest? ive heard of people leaving autos for up to 12 weeks but on the website itsays it should be done in 9 weeks.. so im just wondering if its ready to harvest!

Do you have a jewellers loupe? Or a way to check the tricomes? You're looking for mainly cloudy. With about 20% amber for best results.

Probably another 2 weeks bro. The difference between now and then will be night and day....

ok in that case ill leave it.. seeing as though we have a week of nice hot weather coming up. thanks guys

They always say 9 weeks lol aim for 11. I look for bent over trichomes.
