ORP is oxidation potential reduction... Or Redox potential.
It measures the potential that the oxidants in your water, have to reduce (destroy), other molecules.
It often signifies the quality of your water.
It is what rises when you add Roots to your water, and helps to sterilize your grow.
In your case, you are sterilizing your grow with UV light, AND UC Roots... Your ORP is probably well above 400 millivolts (Mv)... probably dropping your pH to 5.4 maybe 5.2.
ORP is a term used frequently in the water treatment & food processing industry.ORP stands for Oxidation-Reduction Potential. So what is that? The best definition I can give is that “ORP is a measure of the cleanliness of the water & its ability to break down contaminants”.It has a range of –2,000 to + 2,000 and units are in “mV” (millivolts).
What is ORP?
In the world that surrounds us, we do not see it, but there is a continuous exchange of electrons that takes place between substances in the air, in the earth, in water, and in our bodies. This phenomenon is known as ion exchange.
In an effort to reach a state of stability, substances that are lacking electrons are desperately seeking out electrons wherever they can: these substances are referred to as oxidizing agents. On the contrary, substances which have a surplus of electrons are capable of donating their extra electrons: these substances are referred to as reducing agents, or anti-oxidizing agents.
Oxidation-reduction potential, or ORP, is a measurement that indicates the degree to which a substance is capable of oxidizing or reducing another substance. ORP is measured in millivolts (mv) using an ORP meter.
A positive ORP reading indicates that a substance is an oxidizing agent. The higher the reading, the more oxidizing it is. As such, a substance with an ORP reading of +400 mv is 4 times more oxidizing than a substance with an ORP reading of +100 mv.
A negative ORP reading indicates that a substance is a reducing agent. The lower the reading, the more anti-oxidizing it is. As such, a substance with an ORP reading of -400 mv is 4 times more anti-oxidizing than a substance with an ORP reading of -100 mv.
Most types of water, including tap water and bottled water, are oxidizing agents as their ORP value is positive.
Alkaline ionized water is an anti-oxidizing agent, as it has a negative ORP value and it is able to donate extra electrons to neutralize the harmful effects of free radicals on the body. Most other types of water are oxidizing agents as their ORP is positive.
The following video explains ORP and shows the ORP level of different kinds of water.

The pH of the bud boosters are inherently lower and will drive the pH down. This shouldn't be too much of an issue as you'll be slowly diluting as you move towards harvest.
Canna seems to have horrible customer support. You can only really contact them through email and there is no reply aloud to email so if you have follow up questions you have to reask and prob deal with someone else.
I will hit them up though, hard to believe ppm is too high when its anywhere from 300-150ppm (500 scale) at the last week or so of flower
By the way... In case anyone cares... While it is true that as ORP rises with ozone, the pH will drop... With chlorine it is the opposite.
As you add chlorine to raise the ORP, the pH will go up.
Also, the more chlorine you add to make the ORP go up, the more the pH goes up, and if the pH exceeds 8.0, poisonous chlorine gas will be released.
In experimenting with O2 gas infusion on my UC I have experienced the ORP approach 500 and saw plants yellow as a result. It seems the rootzone was over oxidizing causing plant stress. I did notice the pH decrease as well, though it actually worked well to counter the natural pH increase from the release of hydroxyl ions by the plants.
Yes, I am currently trying to control my pH with my ORP.
I started at 330 millivolts to get to 6.3... And I raised it to about 350 Mv to put the pH at 6.2... Still experimenting and dialing it in, as 350mV almost takes the pH to 6.1.
