Why wont my plants stop flowering?

[Situation420]

I got a question, for more advanced people please. I have a strain that was labeled as a 7-9 week flowering period plant (Blueberry Headband). It is now day 72 (week 10). I have been keeping an eye on these plants for a while now and they keep producing new white pistils all over the place every 5 days or so and the trichs are not swollen or amber or cloudy and the smell is not entirely there yet. This has been going on for the past 2 weeks. It's not like a couple, They are all over the place as if there is still 2 weeks left in flowering. Starting about 4 weeks ago my plants have been given a 400 ppm nutrient solution (down from 1200) , mainly just vitamins and calcium in my RO Water and no adder fertilizers. The ppm in my buckets stays between 350 and 450 ppm give or take. They have had just RO water for the last week as well. They have been on 12/12 since the start and just wont get ripe. I mean some parts look ripe but others are definitely not.

Should I just hit em with 72 hours of darkness and cold root zones and harvest em already or keep being patient? Any thoughts on this are appreciated.

I know that I cant go by what the label says for flowering time but what the heck? How can they be this far off? Everywhere I look they say like 56 days, or 63 days tops... I'm looking at 86 days by the time I harvest ( a full month longer wtf!) lol

Too much nitrogen or Calcium. Or too much blue wave lengths. Or its the flinstone vitamins

Is there regrowth on the buds? When you go passed the window. Regrowth occurs especially with sativas. They will be done but appear not to be. Trichome color can vary from bud to bud and the time of the day. Check lower buds right when they wake up.

Could be a multitude of reasons as to why.

Firstly. The days of flowering count. Are you counting days of flowering from the moment you switched to 12/12? This doesn't allow for the transition to flowering, "stretch", most flowering times given do not include this transition phase. They only count from the moment the plant begins to flower.

Secondly. Flowering times are only an earliest possible harvest time. This doesn't allow for ripening to your chosen amberness.

I've got a 55 day flowering fruity chronic juice that's currently on day 68 of 12/12 and they took 7 days to start flowering so that's roughly 61 days of flowering. She's ripe for the Americans among us who want cloudy with little to no amber. But for me I wait until I see more amber than 20%.


Thirdly.
Pistils are only a rough indication to readiness. There are other determining factors.


Fourthly.
Could the new growth or is the new growth looking like its foxtailing?

Fifthly.
Phenotype variations of the parentage could mean you've got a phenotype that takes longer to ripen. Again flowering times are based on the quickest finishing phenotype the breeder found in its stock.




Hope some if these help you out.

Man good point on when Im counting the start of my flowering from and the phenotype variations. These took about 8-9 days before i even saw any budding sites start to form from the time i switched to 12/12, and were stretching hard during then. Secondly, it is a combination of foxtailing and general overall bud growth so i was thinking it might be like that kid that grows another 6 inches when they get to college, just a late bloomer but still a person. I'm going to lean more towards your first, 2nd, and fourth, possible reasons. Actually, I like all your reasons. Good answer dude thanks.

So they will be amber in the morning but clear by nightfall?

 

[skunkd0c]

the time the seed seller states is phenotype dependent so it is mostly just a guide
i do not know why, but some strains will continue to produce new pistil growth
mainly on the main head, but also on other colas this will continue well past full maturity
with these types of plant you will have to harvest them with some new pistils showing
i would not change the light period , just be patient and wait for her to finish
i like to let the calyx swell as much as possible before i harvest, i like the colas to be as solid as possible
i always take samples from 6 weeks onward anyway and harvest when it taste right

peace

How do u take your samples? I mean like drying em out so they are smokeable enough and what your look for?....Also, I'm not messin wit my light cycle i was jw, that was only for if i was about to harvest i would do that as well.

 

[skunkd0c]

taste matters alot to me mate i guess i am quite fussy, if i do not like the taste of it i will not want it no mater how great it is in other departments
i let it dry in the room or somewhere warm its dry in 4-7 days
i can tell if i will like it or not from these samples ,some buds will improve with slower drying and a cure
good buds that i like it will be obvious within a few tokes of a joint of the sampled bud this bud will only get better with a good cure
i normally take cuttings of all females during preflowr, if i test buds i do not like, i also discard the cuttings

peace

yes. light and heat destroys trichomes. they replenish when they sleep. kind of like skin cells

 

[althor]

Same thing is going on with my buddy's blueberry headband. He is in week 10 now, the other strains in that grow have already been cut but the blueberry headband is still kicking out white pistils and no amber crystals.

So does it matter then if you harvest during the morning or at night? Also, I definitely see some fox tailing going on but was also wondering why it is going on all over the buds as well. There are a couple half inch long tails on there but still growing at the end. Im hoping that these plants are exhibiting more dominant sativa traits from the sour in the hybrid and just gonna wait it out and let em get more potent. Maybe these plants are reincarnated Rastas with dredlocks mon and gonna be the some dank dank.

 

[hyroot]

thats why people put them in the dark before they harvest. morning is better than at the end of the day. regrowth or fox tails usually happens when you go longer than should. are you starting to see any ovules forming on the buds?

 

[Bigby]

Some strains just keep throwing out new pistils. Check the trichs with a microscope, that'll tell you more.

Moving the light further away and shortening the day length will both speed up maturing.

 

[Situation420]

I just looked at the trichs again since last week and they are now swollen and about 50% cloudy 50% clear. I guess im just gonna have to be patient and go by that. Since it's a indica/sativa hybrid its up to me what i want the ratio of thc to CBD to be and just have to keep an eye on it. Thanks for all the feedback.

Are these ovules or seeds? I am still unclear on the anatomy. It may or may not have been accidentally pollinated. This was on day #71 of 12/12. It will be day #76 tomorrow afternoon. I am getting foxtails on the half of the crop that is Sativa dominant phenotypes but hardly any on the Indica phenos. Skunk #1 by Sensi Seeds.

Ovules or seeds?
