okay so you had pretty high pH stuff going through the pots
you have corrected it now, by running lower pH through the soil
In my mind, that gives rise to making a lot of dormant higher pH stuff that has been sat in the pot already a chance to be absorbed now - this may or may not be complete rubbish, but it crossed my mind once I’d started pHing my water and feeds
but basically give her a couple of days to stabilise! you’ve made some changes, see how she reacts fully before you react again!
good job so far mate
take what I say with a pinch, just my thoughts!
