OK....I know what your talking about....your ph creeps after 24 hours....are you top feeding on drippers?...what kind of meter are you using?...pen? probe?...when was the last time you calibrated it?......all of this is important.....I use a hanna with a probe in my res...it stays there...but I calibrate it every 3 days....without a meter you know to be accurate...your lost.....additionally there is a realtionship between ph and ppm....so a ph of 6 willl have a different ppm...than your 5.2-5.4 range.....and there is a sweet spot you need to be around...not necessary to hit it every time...but be around it.
Also...are your organic or synethic nutrients...it makes a huge difference in coco...as far a your relationship ppm vs ph....
how ofter are you watering/feeding? what is the size of your pot?.....it all matters.
to calibrate....get you a bottle of cleaning solution & a bottle of ph 7.01....set them on your counter near your res...since I use the probe...I pull it out of the res...shake off excess...put the probe right in the cleaning solution...get out my cell phone start the timer for 2 minutes...then drop into the solution...pull it out at 2 minutes...put it in the ph 7.01...and wait 2-3 minutes....then recalibrate---it if needed....then drop back into your res......I suspect your meter is off....and your ph is really 4.6-5.0...which is way low.
another thing almost all ph rises in the res after 24 hours....just the way it is....I water at 5.6-6.0...and when I come in and check it the next day for watering....its always 6.4-6.8.
lastly....the water from your water company changes all the time...mine is real bad right now...lots of chemicals...and that will also effect outcomes..espically when your ph is low......when vegging...ph at over is 6 is fine.
for cal mag additives....I use a combination of glaicer rock dust and molasses...not together...teaspoon in the coco of glacier rock dust...and at week 4 water in molasses every other watering......my plants are way happy....everying I use is organic OMRI certified....
I know I rambled quite a bit....but without that meter I would be lost....now its the first thing I turn on when I go into my room....also I have a mixer that mixes the res...I let that thing run for an hour before watering....you could check your ph at the start of the morning...but when mixed...that is going to change by a bunch...before you ad anything.
good luck....sorry for the ramble.
