My gh flora nutes kinda do this to me. I grow in soil and when I mix my nutes all up I ph them and sometimes I will forget and go do other random crap in my house. When I come back, what used to read 6.5 will always be different. Lower and or higher by a few points. I used to think it was my meter but that is dialed and I checked it with calibration fluid. Also, I can measure my nutes to 6.5. Throw on the cap shake for another minute or so and it will be slightly off again! WTF!
I just try to use mine asap after I measure and correct ph. Not sure if anyone else had had this issue with the gh line or if its known for that but mine tends to be super finikey
all the PH up that I have come across is Caustic Potash. This is potassium hyroxide mixed with water. It is commonly known as lye.
I cannot imagine it is good for bacteria in any way. Could be wrong in this but, I cannot imagine something that caustic as being good to living things.
If your ppm is droping and your ph is doing the same, you have a ton of bacteria in there! Too much probablly.
I would say it may be your bacteria count causing the fluctuations,as different types cause different reactions with the nutes,some are aerobic,needing oxygen to survive and some are anerobic,not needing oxygen,in these we find also some take out nitrates and phosphates and some add them in the form of protein conversion,which will cause a drop or a rise in your ph,
You caused a bacterial bloom, which in turn caused pH to drop (fairly precipitously, too, I wouldn't be surprised if they're mostly dead now). I don't know how much of a shift these groups of microbes can take, but eventually, yes, a shift large enough will absolutely kill them. And if it doesn't kill one group of microbes (the myco you mention means to me mycorrhizae, which are fungi, not bacteria) it most certainly will kill another. But to quantify any of these statements well would require a microscope and start/end counts.ive had 20 gal mixed nute solution sitting steadily for a few days (with a huge airstone) at 1000 ppm 5.8ph about 24 hours ago i added like 6 tsp of ZHO and 4 tbsp hi brix molasses. today when i checked the ppm was down to 950 and the ph fell way down to 3.8
is this norml?
does the ph up kill the bacteria?
does the huge ph swing kill them?
The microbes are eating the molecules that can be measured via conductivity. PPM is simply a conversion of microSiemens/milliSiemens (uS/cm). Organic molecules are not all conductive the way chemical salts are, so when you're measuring ppm you're really not getting any sort of accurate picture of anything except whatever molecules can conduct electricity.the ppm continues to drop as well.....
down to 860 now
whers my ppm going and whys the ph dropping so fast?
