67 days into flower Nirvana Northern Lights no amber. How long left?

So these plants have been in flower (pistols seen) since november 2nd. I had to go out of town for the past three weeks for christmas so they have been by themselves that entire time being watered by my tropf blumats. These plants have ZERO amber on them and given that I have reached 9 weeks I am wondering if these look like they are going to be ready to harvest anytime soon to you guys. I just added the LED lights so disregard them from the equation. Also the plant in the 5th pic of is 4 weeks behind the others and looks absolutely terrible. Do you all think it is a lost cause or just lagging

Well man, got to say it is looking beautiful. Although I really am surprised you cut ALL the leaves off... Lol wtf?

Get a x25 microscope (jewelers scope) and you will know when its ready. Some plants go well into 15 weeks. But you will probably be ready in the next 2-3. Happens quickly so keep watch on those trichs!

Actually I didn't cut any of the leaves off. They all just fell off when I got back from my 3 week vacation. A side effect of not getting any attention for 3 weeks I guess.


edit: I have a 60x loupe and a 30x loupe so im covered in that regard. Its just that I always see peoples finishing times at around 70 days and mine is 67 and doesn't seem anywhere near done.

were the clocks in your house flashing 12:00 when you got back lol? ...it almost looks like they were sitting in complete darkness for a while and/or the temps dropped really low...maybe your place or something in the setup lost power ?....just a thought..

9 weeks since they flowered or since 12/12 light flip?
I think they look pretty good, close to getting done. You say no amber, and I see some newer pistils in photo 2. Are the trichs cloudy at all?
There are a couple of good sticky threads in the 'harvesting & curing' section that talk about a plant looking 'done'. It is not all about the trichs. I do look at the trichs for cloudy, and try to get 0-5% amber.
If you go another week with no change, you could be done !

I've grown it before not from Nirvana, and it was a 10 week finisher. Patience, it won't be long now. Keep checking those triches. Looking good!
 
Nughunter --Temps were most likely low as its wintertime here and I wasnt able to constantly monitor them.

Mrwood-- Its 9 weeks since I saw pistils and there are some cloudy trichromes but not many.

And would you all say that ive already hit that end of growth growth spurt or should I expect more to come?

not sure if your exhaust and fans run when your lights were off...but im going to assume when the lights went off..your fan and/or exhaust were still running? ..either way it looks like the temps dropped and they got chilly bro..still looks like a nice harvest ..epsecially since you were not able to baby them for almost a month ..as far as if they are done growing..i would give it another week and see what happens..now that you are back and can monitor the room... if the cold was a problem atleast they will have time to get back to developing a few more tri's before they get chopped !!

Yes - the vertical stretch should be well over, but your buds may fill up a bit. At nine weeks you should be getting close. If your temps were low for three weeks, you may have retarded your plant growth some.
Just keep going & monitor your plants !

i wouldnt take it much longer... ive been in huge arguements about this. after fighting on the side of "more amber is good" for a while i realised i was wrong. after this year's harvest i see now that its better to harvest at around 10% amber. the thc still decomposes into amber while its curing and drying. ive ruined my nirvana white rhino and nirvana blackberry plants before experimenting with that. i

when u stress a platn to the point of extending the flower period, sometimes they never quite finish too... THIS MAY BE YOUR ISSUE. go search for the thread called bhutanese timpu or whatever its spelled. the dude has a plant at 14 weeks with no sign of being anywhere near done. he had stressed it to the point where it was ever going to finish.


think about it... the plant is keeping itself at the point where it is most likely to still produce viable seeds. which normally would be 3-4 weeks into flower. u said u stressed it out right around there too. consider this info a bit.

Well I can say that I am getting an extreme amount of new pistils as of today so hopefully it is finishing up.
Some times a strain will just continue throwing out new pistils even after trichs get dark. At a certain point you will just need to decide when to pull.

Well as of now there are zero dark trichs and I went over them with a 60x loupe for quite a bit today. Ive got my fingers crossed ive still got another 40% of mass to come haha.
