Pineapple Auto- (first ever grow)

Possible ph issues came out of nowhere on the Bestva plant. Even though I have been ph’ing the water to between 6-7 every time now. Most of the white hairs are gone and I’ve just been feeding and watering while watching the trichomes. I would imagine I have two weeks left ( based on my zero previous grows hahahaha) so I’ll stop feeding altogether after this last one Smelling awesome, keeping an eye out waiting for trichomes to show any amber but not yet. Still struggling to fix the feed or ph or whatever has been causing the discoloration etc but haven’t made much progress. Don’t know if my ph pen is out of calibration, it’s because they’re ending their flowering cycle or what Going to start flushing soon so I won’t worry much about anything besides ph
