Here is my opinion on this one ... I would say its ready.
The triches are cloudy by overall percentage ....
Not sure if this an AUTO ... BUT if we crunch the numbers
Say 30 odd days to veg and preflower leaves 74 days flowering ( based on 104 TOTAL GROW DAYS )
Which puts your flowering at 10 weeks going on 11. That is the time frame most AUTOS run their life. Usually 70 days or so is the typical time for me .
I like cutting them BEFORE seeing ambers .... Just by TRICHES NOTHING ELSE.
If triches are cloudy or near cloudy ( NOT CLEAR ) by at least 50% i will cut.
( what i mean by this ... Every trich i can see AT THE BUD is AT LEAST partially clouded or fully clouded ... I chop )
Soil : I dont necessarily FLUSH since i just use water ANYWAYS a week or two before harvest.
Hempy : i dont flush since perlite mix would be washed thru everytime i water with PH WATER AT END ANYWAYS.
