Question about fan leaves day 60

[Zephyrs]

Ok so this has been my first autoflower I've ever grown. She was fast, furiously growing, super healthy with a preflowers at day 20. Well now I'm at about day 60 and my fan leaves look like something from another planet, I mean they went from lush green to all kinds o funky looking in a matter of about 14 days. Question is, 1 Is it a p/k lockout issue? Or 2 is that how autoflower fan leaves just naturally fade late in flower? Or 3 did I fuck something else up? LOL
The plant is a fastbuds wedding cheesecake auto. In a organic soil mix. Under a sf1000 at full blast 22 inches above canopy. Only watering with molasses water every other normal watering. Help an old grower with this first ever autoflower! The first picture is from 12 days ago. The second 2 pics are from today. WTF

I have to little knowledge to actually give advice but... questions others might ask to help diagnose...
Sense your organic, have you topped dressed or used any teas in last 14 days?
Any environmental swings?

Good luck. Hope to see your problem answered

Edit: just noticed you wrote "only water and molasses" sorry

Good question! Because I forgot to mention that I also gave a mosquito dunk solution on the top 3 inches of soil almost about 10 days ago. Now I'm starting to think that might have thrown something off. The mosquito dunks were for a fungus knats problem when adding new layer of soil, late in flower.

OOOO. Glad I could help add forgotten info

Dude, your plant is fine besides a few burnt tips. This looks like perfectly normal ripening color change to me, some strains do it, others don't.

Ok well thank you for a little stress off the shoulder lol. Yeah the burned tips are from my bottom layer, that I amended with a wee bit more dry p/k nutes pre planting. Also I put the sf1000 in at day 30ish. Which replaced an older model blurple. So I did light burn a couple sugar leaves. I was just concerned about the blotter kind of coloration though?? If I saw that late in flower on one of my photo periods plants, than I'd probably have a fuckin heart attack!

No worries, burnt tips aren't a big deal. It's just something to try to avoid in the future by tuning in your grow. Keeping your leaves as healthy looking as possible is a great goal for producing quality bud in the end. Some people try to "push" higher and higher EC onto their plants thinking they will get bigger buds, but all that usually happens is the quality suffers. Your plant looks good, enjoy the pretty colors!

Thanks Much there Buddy! I will update when I hit day 63. But she starting to throw another round of white hairs. So it might be another 10-18 days before harvest, maybe??

I’ve noticed this too. I suspect it’s a couple of factors. Natural senescence of the plant and low pH.

Ive managed to get a few autos to never fade and that was all due to properly liming the soil.

The moment we hit flower and start adding more P and K the root zone acidifies. This needs to be balanced by lime or some other buffering agent.

Thank you @Nutty sKunK, that make sense now. It's just this never happens to my photo periods. That why I was kinda trippin. Do you think the mosquitoes dunk drench i did about 10 days ago might have spiked my ph level to high or to low suddenly??

I agree it looks just fine. Leaf purpling can happen from fluctuation in temps. It can be genetic too. I think you will yield some nice bud friend
