I ask this because if you’ve properly reduced day time temps, you are assisting her in further ripening. Not just the addition of extra P and K. But temps play a vital role in maturation and production of resin, terps and density.
If you have not dropped temps and they have been consistently the same all grow, she is constantly in grow mode with winter not in sight. She may think she needs to keep making buds and not focusing ripening for last chance before season end, she doesn’t know it’s nearing the end. Cold temps will ripen her up nice and quick for you and give you those qualities. She is aging but she isn’t ripening.
You may see new growth and accounting those white pistils into your calculation of overall % amber. But if you don’t drop temps, she will keep trying to pump out new bud growth. Stop growth and drop temps to trigger her end of cycle; which only increases potency, aroma, flavor and density.
Just saying this might be a cause for prolonged flowering. You’ve maybe not triggered her awareness of the e season ending. If your temps are not lowered, and your light is still maxed out, she has no idea so she keeps trucking. Be wary and look for herm as you tip the harvest window.
In my experience, if you have a reduction in trichome or halt in trichome production, you’re too warm and she isn’t focusing those attributes as her last stand to be pollinated.
Read up on what makes a plant sense end of season and mimic that. Colder days, less intense light are two things to consider if trying to push her to harvest window and trichome readiness. Flushing or reduced feed can also be a trigger of fall with water washing away nutrients.
Some may not agree but let be real, you get less potent buds running prolonged same temps until harvest. Plus, beyond harvest window, she is just waiting to decide when to herm based off time and not environmental factors. Internal time clock due to 12/12 with no reduction of intensity of light.
No adjustments late in flower=prolonged growth and not ripening. You don’t have to believe it, but you should consider these factors. Indoor, you do all the work of this and are responsible. If you just let it go and no adjustments respectively, you won’t ripen up before she gives up and your end product suffers from neglect. Sometimes products like Ripen help to trigger hormonal, but if conditions are not met, you just sacrifice the best time of the plants life to give you what you want, high potency, tasty, smelly, dense buds.
