Bleaching?

I've not had sugars go yellowish in the past. Mainly top buds, closest to the light at 19" away. I've had the light as close as 16" in the past. All other leaves look nice and healthy. Just the little sugars. Only the more mature plants.
Is this bleaching or autumn colors, formerly known as late-stage flowering? Third day after ten weeks since seed to coco. Only flowering nutrients for the past 4ish weeks. Leaf temps 67°-71°. No clue about RH. 6.0 pH.

I blew up the photo and I'm sorry I can't see it well enough like you can, but I have an idea of what you might be going through and so this doesn't sound completely crazy I'm backing it up with a photo. So I started having my tiny little leaves turn white and I mean seriously bright white like it was bleached, the bud also turned white and before the grow would finish they looked like tiny little white roses. Only the top cola's did this and it wasn't light bleach, I had more experienced growers see it for themselves in person and they all told me it was called "Hash Tips" and referred me to a High Time article at the time which was recently published at that time. I can tell you I thought the green stuff was good, but when you bowled up that white stuff, it was time to sit down and not plan to go anywhere for awhile. You can see by mine that's not camera flash, and they didn't look that way until they matured and got near flower.

I see the lighter colour on the very very top sugars. You sure they were dark green before all over? Got pics from last week of that bud?
 
Same plant, different bud, last Thursday. Same thing is happening. It's been pretty slow going.
I'm starting to think it's just late stage issues because buds 6" farther away are doing the same thing and other buds as close or closer on other plants are not.

So you're saying it's not likely light bleaching, which normally shows up in the top pistols on mine....probably just late stage, the larger leaves are losing color too but going dark.

If you're giving nutes you could try dropping them back a bit but I don't think it would matter all that much.
 
Pistils are as ginger as they should be. Those that aren't are still fresh.
Symptoms of light stress I see online are all over the place and I have and have had a few of them. My leaves in question are tucked in. I'm figuring I would see more damage around the area than I do.
The older, darker leaves are also getting waxy and brittle.
