(Pictures) Unknow strain need advice on when to harvest

Unknown strains
Outdoor grow 100-110 days old
Unknown start date of flowering
FFOW medium, having to water daily, you see the grass. hot
They smell dank as hell!
How much longer should they flower for?
Should I just go by the trichomes, clear, cloudy, amber idea

Thanks for any advice

Not yet.
2.. maybe 3 weeks would be my guess.

you will know when it's time to harvest, but in IO looks to me there only been flowering for 2 to 3 weeks minimum so depending on the strain be it a sativa or a indica. could be 8 weeks Sativa or 5 weeks for the Indica. Just keep an eye on them when the Trichomes become milky to amber break out your choppers and chop it down.

Maybe Day 37 of flowering based of multiple responses from earlier post.
They got my whole back yard smelly. The one next to it started showing female signs so i left it next to the other.
The lighter pictures are most current, 37days

Looking good keep up the good work

Your about a Month away from harvest. That bitch has just begun flowering.

Day 57 of flowering outdoors grow. I know the leaves look Yellow. I didn't start of with any nutes, just FFOF soil. I see my plant is deficient but I didn't want to start giving nutes right in the middle of flowering. I'm thinking if I did give nutes she would be bigger. Two more weeks?
