In 2 days into week 9 and a couple of plants are fading to yellow. Is it too early to see a fade?

Details
Led hlg's
Temps 26c... day 23 night
Rh is about 50% ish... hard to get it dryer
Coco
Ec was 1.8 just reduced to 1.6 last week
I also shifted ph from 5.9 to 6.1 a week or so ago

Had some issues with heat a few weeks back so some foxtails left from that.

Should I be seeing this yellowing?

Some strains yellow and change colors like a New England fall foliage.

Keep your RH low and why did you change your PH?

lower PH as the grow progresses. In DWC I'm to be around 5.7PH in late flower.

Slightly higher ph is better for p and k uptake. Quite a few charts suggest shifting to a slightly higher pH in the last few weeks. And a few people on here have also suggested it.

The strain that I quite yellow is skywalker... its a mixed grow. Also a bakers delight is also yellowing

The buds look nice @oill . It doesn't look too bad to me and you're not doing anything wrong that stands out. You're feeding them well so it could be just the plant ending it's life cycle.

Thanks guys it's appreciated. Yeah they look OK.. m just seems a lil early. Defo struggling with temps and humidity... my dehu makes the nights too warm and can't run dehu and ac at the same time.... my grows are easier in winter for sure

The fading would be splotchy if it was a mishap. These have a nice subtle transition going.

Makes my mouth water.

** imo it's late to raise the PH. By this time I would have been lowered back down to the value I started. This is just me I wouldn't go changing anything where you are with it now. Nice plants.

I assume it's the top down fade that is throwing you off?

I notice it is the light penetration, or lack of, that will leave the lower fans more green for longer. They are shaded.
That is my best conclusion. In all honesty though the top down fade is a mystery to me beyond the light penetration.

I have seen people take the tops as they ripe and fade the lowers.

Cant be fucked with part cropping.... Will wait a week or 2 more and crop all together taking the repeat first... probably take me 2 days to chop.

Everything is looking OK is just lacking the density I look for... down to the heat issue. Attic grows suck!
