Ph will not go down

Hi, this is my first time posting. I am a fairly experienced gardener and I have come across a problem I just cannot solve. My plants are in a coco perlite mixture, with beneficial fungi, being fed House and Garden base nutes with a few additives. My clones started having a lockout issue about a week ago. I immediately started flushing them and found the ph of the coco to be around 7 on average. I have poured literally gallons of ph 5.5 water through my little babies. They are in 4x4 plastic planters, standard. The ph will not go down lower than 6.7, and even raises back up to 7. I have done this twice, with 2 days between. It is not my ph meter malfunctioning, as I suspected that and went and bought the nicest one at the store to replace my old one, and it is freshly calibrated. Any ideas on what could possibly be causing this? Thanks :)

are you letting the water sit for 24 to 48 hr before using?
