How often are you watering them? Also what nutrients are you using? I would say the probes are not super accurate usually. Your better off making a slurry with some coco from the pot and distilled water and then ph your slurry.
They are currently in 750ml pots and I’m only feeding 250ml at a time, so they are drinking that over 24hrs. That’s from wet coco to fully dried out.. I’m using a range called CX I doubt you’ll know of it.. okay that sounds like a plan, can you run briefly through that for me? I’m assuming just take equal parts or the like and mix it up and ph that? Is this after feeding or dry coco? Probe or Pen, I’m using blue lab ph equipment..
Here is a good thread to explain, just substitute coco for soil

Soil Ph Slurry Test - Step By Step With Photos
Knowing the pH of your growing medium is important from time to time. The soil pH slurry test is the easiest way of finding the true pH level of your soil based growing medium. For this you'll need: pH Meter - Cheap Amazon pH Pen - Blue Lab pH Pen - Blue Lab Soil pH Pen Cup or Container -...
Also you should not be letting your coco completely dry out. You actually want to keep the coco about 90% saturated at all times. You may think about watering twice a day if they are really dry in just 24 hours. Letting the coco dry out maybe part of your ph issue here, it can definitely lead to salt buildup in the coco.
