Starting this week I will also add Oxygen granulate (KMPS, CAS-70693-62-8, 2KHSO₅ * KHSO₄ * K₂SO₄) I use this once a day to reach ~250 mV on my ORP meter, it is not calibrated so it more of a good guess, adding this helps to keep the reservoir stable even with higher nutrient temperatures in summer and it also adds a little Kalium/Potassium for the plants.
The ORP probe is not calibrated and values are to be taken with a grain of salt.
Values are average of the day.

@Lukush, Thanks :)
Well your NL grow is 4 years back but I checked your other grows as well and now I want a SP6500 :D
If I am allowed to give some advice I would suggest to use up your nutrients and then switch to something cheaper like (US based?) Jack's 321 or commercial ones like Yara/Athena because Advanced Nutrient has a good branding but is EXTREMLY overpriced.
I pay ~ 1/5 compared to Canna and probably even better pricing compared to Advanced Nutrients.
You can mix your own stock solution in the old containers just check Hoocho on YouTube he made a pretty good guide about that.
40ml A + 40 ml B + 10l tap water gives me with my specific tap water ~ PH6 and EC 2, super easy to use.
