When should i harvest?! Pics included

This plant was put in soil on APRIL 25th, so basically it has only been growing for little over 2 months. It is an autoflowering ak47. And i am skeptical about harvesting because of the nature of its rapid growth cycle. My last grow was 1 plant and it took from August-December and nothing was trivial about when i should harvest. It was sure as shit obvious.

But this one has grown so quickly and im not sure if i should give it until the end of August to harvest.

I actually have 5 plants but this is my oldest one, all the other ones were planted on May 4th.

it's hard to tell for absolutely sure without some closer macro shots, but i would say you could harvest that in a few days

i would give it 48 hours of darkness in 1 day

Holy shit really? I didnt expect it to grow this fast so i was gonna give it until like late July/ Early August.

Idk should i actually give it for more time?

nice....
check your trichomes.
just guessing when, is not a good way to tell if they are done.

Dont guess. Radio Shak 10 dollars 60x scope. !00% guaranteed to know when to harvest

If your guessing though, I would give her at least a couple WEEKS. Not days... I see no signs of it finishing up

I have a scope, its a loupe and it has the 2 little tiny led lights on it. its pretty good, but i'll go to radio shack and get the 60x aswell

Any other thoughts on when i should harvest?

The oldest plant looks ripe to me, I'd start flushing and give her about a week then CHOP.. Can't tell for sure with the other plants

Idk cuz the buds still seem pretty small. Its almost like the buds dont look fully grown.
