They look soggy.
The yellowing is from being too wet.
Your PH is off probably due to the salt build up / oxygen deprivation from over watering.
Let them dry out and then really flush them ( using 1/4 strength nute solution )..get that crap out of there.
If you buy half way decent soil you don't need to ever bother checking PH...I never do anymore.
And the PH of the soil is going to drop eventually..especially late flower. ( Salt build up, flushing of buffering agents...lime, calcium etc )
Perfectly normal.
Also certain minerals, Phosphate, for example is better absorbed by the plant at a lower PH then other minerals.
Last time I ever checked PH ( years ago ) late harvest... low to mid 5s ? Can't remember exactly.
Again unless your doing Hydro...and you buy good soil, there is no need to bother with PH.
Just don't over nute, over water and when watering you should have it pouring out the bottom...not just a few drops.
Example for every gallon you should get like 1/2 quart come out the bottom. This cleans roots, washes away salts, oxygenates the soil and ensures a thorough watering.
But I would suggest letting your girls dry a little out first.
