Pro-TeKt pH problems

So, I use to use MaxiBloom as a base nutrient, but then I switched to FloraMicro + FloraBloom; Pro-TeKt was great for balancing my pH before, but now I just want to kill babies.

No matter the order I add things in, pHing the Pro-TeKt alone, whatever, I hit a wall at ~6.0; however 12 hours later the solution drops to 5.2; but wait, another 12 hours and it's on the rise again (no plants)!

I see a lot of threads with people claiming five to ten minutes for stabilization, but even when it's R/O + Pro-TeKt + pH Down ALONE with no nutrients, the same shit happens - I did two buckets side by side.

What the hell?

I've read a lot of threads over the last sleepless night, and perhaps I've missed the ones which actually matter, but most simply say it works or it doesn't, with no useful information whatsoever.

EDIT: Called Dyna-Gro, spoke to one of their scientists, he had no answers; awesome.

you are trying to ph a solution with no ppm. theres no buffer therefore you will have a fluctuation.
add ph down first, then nutes, then ca/mg.

Nutrients:
1. FloraMicro
2. FloraBloom
3. Floralicious Plus
4. TriveAlive B-1 Red
5. Epsom Salts (noticed a slight sulfer def in clones)
6. Calmag
7. Fresh Microbial Tea

I've added them in all sorts of orders, I just got clones and I'd rather throw away nutes experimenting (separate buckets) than throw away the crop (it's also more cost effective). I tried adding it first, pH, nutes, additives, tea, pH; first, nutes, additives, tea, pH; nutes, additives, tea, calmag, pH; and, probably a few others... always the same extremely slow pH change from over buffering and then moving through the tipping point, and then moving back to the buffer, etc...

Answer: Faulty pH electrode, the solution came in at exactly 5.75 after replacing it.
