White Widow Auto harvest timing and leaf color question

Grow Cycle
1

Hi ILGM pros! I wrote for help many weeks ago when I was struggling with my first seeds and this community was fantastic. Despite stunting her early on with my poor water / light management, she survived and grew (although her timing may be a little long and buds smallish due to the stunting). Now I’m back with a couple questions at what I think is nearly harvest time.

Today is six days into Week 13 since sprout (so Day 90) and roughly Week 5 since flower (so Day 41). Her leaves were dark green and healthy the whole time, but over the last few days some leaves are getting lighter and others are turning purplish / reddish. So my questions:

  1. Is this just the plant wrapping things up and prepping for harvest or are there other issues I should try to address?

  2. If close to harvest, thoughts on how much longer?

I tried to get some closeups of a few flowers and the overall plant. Any guidance much appreciated!

Details: White Widow Auto, Happy Frog soil in 3 gallon fabric pots, Fox Farms trio at 25-50% from Veg to now, VIPARSPECTRA 2020 Pro Series P1500 LED, small circulating fan, AC Infinity CLOUDLINE T4 for intake / exhaust, minimal and late LST, pH and ppm within recommended range but haven’t tested runoff in a couple weeks.

I’m not an expert but I would say you are close but still a few weeks away lots of white pistol and color could be from temps dropping or fluxing more than 20 degree just my opinion but looking beautiful there

I am not a pro either but to me it looks like you have a bit of time to go and may have a pH or p,k issue possibly

Thanks! I don’t think it’s temp since it’s inside and stable. Yeah I agree I’m thinking at least a week or so away.

Thanks! pH IN is same as always from my well water at 6.4 - 6.7. Just flushed and checked pH OUT today and it’s low 6’s so it shouldn’t be causing big issues. Going to try upping the last couple Fox Farm feedings from 50% to 75-100% to see if adjusting nutes has any impact. Otherwise I’ve seen lots of posts saying this kind of coloring happens near harvest time for some plants. Wish me luck!
