Nutes look a little hot, it’s probably her just starting to fade out.
Have you been watering to runoff to avoid salt built up? Fox farms has been known to be heavy in the salts.

Runoff pH and PPM?

Yeah my run off is running out at 6.3 ish
I have no clue on the PPM , I just been going off fox farms feeding chart . Been only giving 3/4 of wht it says to give . My second grow ever with this
If don’t have a way to check EC of runoff you could do a good decent watering with good runoff of RO water and then feed with half strength.
Me personally I think you just have some salt built up.

Would be my assumption with the PH in range and no PPM readings

So a flush is needed ?
It’s hard to say much without knowing runoff pH and PPM. Your pH is most likely low at this point in the grow. A mineral salt buildup (typical with the FF Trio at this point) submarines your pH and creates nutrient deficiencies due to a pH lockout.

My run off ph was a 6.4 sorry for not having a ppm for better details .

Leaf degradation is normal mid to late flowering. It seems a bit early with your plants, but not too surprising. Suggest getting a PPM meter and manage your nute dosing to achieve a consistent ~1,000 PPM.
Your pH is fine. It will drop over time, so come back and ask how to manage it when it happens.
