Is my plant dying? Can I save her?

Hey guys, I'm a new grower, I typically read the posts here in search of answers. I figured I'd share what I'm dealing with to see if anyone can help me.

Set up: hydro - DWC
Strain: Black widow og from ILGM
Nutrients: Gen hydro flora series with other gen hydro additives.
Date: week 6 of flower day 44 of 70 day harvest window
Ph: 6.6 ppm around 1200 (I lower it to 5.8 almost daily)

Issues: ph keeps rising (most likely from armor si) but every time I lower it, it creeps back up the next day. Plus the temps keep climbing to around 81F with rh of around 45%-50%
I went out of town for a few days and discovered her looking sad droopy and just practically dead
I'll include pictures of my findings

Trichomes are still developing and haven't quite turned cloudy yet. Buds are okay I guess but all the fan leaves are wilting. Plus the roots are healthy looking, no sludge or rot or even foul scent.
Am I misreading the trichomes? Is she ready for harvest? Or she simply just dying? Kinda panicking... I appreciate any help

Your right about trichs,not even close. I have no experience with hydro but cant help but say I've never seen a plant in hydro look so thirsty? I'm curious to the answers your given

Why is ph changing almost a full point daily is something I'd ask myself i think

That's my question as well lol I'm thinking it's got something to so with Armor Si. I might just flush her out a few days to see if that helps

ph rise is normal. she is dying for sure.

Did you look at the roots ? something is wrong in there... prolly too much light also but i highly doubt thats what killed her.

Hydroguard or something like it, use per directions. There is something cheaper, but Idk what it is.
Rootrot is what that seems like to me. You can smell it as well, won't mistake it.
I had it in my 1st grow. which was a 5gal and an airstone. I took the plant right outside and washed the F out of the roots and took all the dead roots out. It recovered and finished.

I don't know if the washing is needed, but that's what I did.

Edit 1. Oh, you say the roots are healthy? idk, is your ph meter calibrated and do you have another way to check it.
Edit 2. Armour Si will actually fall out at 6.5ish ph. I have seen the cloudy in my clean nute res before when I let it get close to 6.5.

It could be the ph fluctuation and the amount of ph down they're getting.. Hydrochloric acid?
I killed a plant like that along time ago.. If the roots are good there's hope... Straight H2O for awhile see if they respond.. I never go above 1000ppm.. Good luck

Thanks for the solid advise! That's what I'm doing for the plant now

It definitely looks like root for to me, especially that some parts are droopy and some are not. Maybe fusariam or some other fungal disease?

Oh my, poor sad girl.

Don't show us the car without letting us look under the hood.

First problem is the wild pH swing... that you are forcing! Change the nutes and let it ride for a couple of days and monitor recovery. Don't keep zapping her daily with ph down! Nearly a full point swing every day has her in shock. Those leaves reak of a ph problem.

I'd flush her with ph corrected water, wait 24-48 hours and begin feeding her lightly again as soon as possible.

It's possible it's fusarium but typically it'll take out part of.the plant hard and not be so "uniform".
