Despite growing in soil you need to lower pH a notch. 6.5 to 7 pH range for tap water. pH of run off is acceptable I guess but overall I am not surprised to see yellowing as nutrients get partially locked out over 7 pH for watering. Lower pH a tad IMHO and see where you are in a few days. I use a few drops of cider vinegar but my tap water is 6.9 to start with.

While I wait for new pH meter give less liquid ferts (to avoid pH problems) start from 7.3 then don't know where it goes prob somewhere between 6.6/6.Hi! Lower leaves=N def caused by flush prev week (due to build up), crispy yellow tips=P def? pH pen dead, watering blind, that's the main problem, using pH strips test.... 🤮 EC in 1.5 runout 1.9. Using Solid+liquid ferts (low dosage rn). Still stretching, looks healthy. Agree?
