when i can harvest my autoflower?

You got yourself a kick ass plant there , I would say you got atleast another 2 weeks to go tho before you can harvest this young lady . The reason i say that is because your still have an abundance of white hairs coming out your flowers which leads me to believe that you still need abit of time . Usually an auto flower strain flowers from 6-9 weeks depending on the strain . most of the time it ends up being around 7 . I would start slowing down on the amount of nutrient feeding you're doing and just start feeding with PH corrected water . You can also buy a portable micro scope from your local hydroponics store or amazon even for like 10 $ ( https://www.amazon.ca/Carson-60X-120X-Lighted-Pocket-Microscope/dp/B00LAX52IQ/ref=sr_1_3?ie=UTF8&qid=1542978980&sr=8-3&keywords=portable+microscope ) This will help you see if your trichomes are clear/milky/amber and will also help you determine when the time is right to harvest . Like I said your a couple weeks out for sure still so you might wanna consider slowing down on your nutrients and getting ready for your flush . I hope this information serves you well on your journey to the finish line! -Happy Growing!

Hello @sown420 ! If you want to know for sure you need to check the trichomes with a microscope like this one ( https://www.amazon.com/Forrader-Pocket-Microscope-Currency-Detector/dp/B00JEKXBQ2 ). Start flushing when you see the first amber trichomes and harvest when the trichomes are 80% milky-20% amber for a head high or 80% amber-20% milky for a body stone feeling. Personally if i didn't had a microscope i would start flushing next week and harvest in about 2-3 weeks. Happy growing !👊

All about the trichomes man. I've grew about 10 autos over a couple years. I'd say you have atleast 2-3weeks left when you have more brown hairs than white id start the flush

Very nice plant. The first advice I can give you is to stop all nutrients at this point. There are a few tells that show that the plant is ready for harvest: the pistils (hairs) retract and turn yellow or red; the calyxes swell (the calyxes looks like little balls on the buds and are where seeds would form should you pollinate the flowers). From your pictures, I would say a week, maybe 2. Of course a jewelers loupe or handheld microscope would be ideal to check thricomes maturity.
