It isn't heavily aerated, and there isn't a plant growing in it. If you could be bothered to take the time to read my post, the water is sitting in a bucket. Does epsom salt act as a buffer?

You know what I was speaking in general, to try to HELP you rule out problems. Until you fix your recurring attitude problems you seem to have with me in specific, you can go watch your plants die buddy.
They do look like they're going to die, don't they?
Generally, and i do mean generally, if the pH keeps rising, the mix is too light, conversely, if the pH keeps dropping, the mix is too strong. Generally (all things created equal, and you havent changed variables).
But, if its just sitting there in a stale bucket, i dont think you can assume it will stay stable (i guess this depends on the mfg, and what they recommend) Generally (here i go again) you should only mix nutrient solution, that you can use immediately.
Also, epsom salt caused me nothing but 'ph swing trouble' in coco, but i have seen others use/recommend it.

Buffers in tap water will change the pH regardless as to what is mixed in it.
Information about bubbling is obsolete since the EPA forced municipalities to switch from chlorine to chloramine. chlorine is very volatile and evaporates easily. chloramine isnt and does not.

"wait what", you mis understood my post I think. I mean if the grower sticks air stones in his tank prior to pouring it on the plant, it will bubble co2 thru it, which will raise the PH.
the pH will rise in a healthy recirculating hydro system
the pH will also rise when a jug of anything mixed in municipal tap water is left alone. the buffers in tap water keep the pH high so it doesn't leach whatever the pipes are made of into your water
if you bubble long enough, the pH goes DOWN as carbonic acid is formed.

my tap water has low alkalinity and is soft. EC .2 and the pH is around 7.5 in the winter and spring and rises to 9 in the summer into fall.
When I use FNB or the H3ad/Rezipe with GH or even 5:10 with GH (near perfect match with FNB), young plants in pure coco medium require more Mg than is supplied by the nutes and water.
Similar to what delta9 described on his thread, it's usually only a one or two leaves at the very bottom and increased watering seems to help.

I would never trust those glacier machines out in front of Safeway. I recently read a report about their quality here in San Francisco. After a test administered two environmental safety groups, they found 90% of the machines were not producing the water quality as advertised. Testing water is a high expense, an expense that RO machine companies would probably avoid. If you send it to a professional third party lab it costs between 140- 170$. And not that I loiter at Safeway or anything, but I've never seen one of those things being maintained. Here's the article:
Water vending machines targeted by lawsuit
ETHAN RARICK, Associated Press Writer
California water-vending machines tested last summer failed to meet state standards for chemicals about a third of the time, according to a report by environmentalists. "Buying water from a machine in California is like playing a slot machine: You can't be sure what will come out," said a report released by the Environmental Working Group and the Environmental Law Foundation, which checked 274 machines operated by Glacier Water, Inc.
The Environmental Law Foundation planned to sue Vista-based Glacier Water Tuesday in San Francisco Superior Court for an unspecified amount of restitution for consumers. The complaint also asks that the machines be taken out of operation, said Jim Wheaton, president of the Environmental Law Foundation. Glacier Water is the state's biggest operator of water-vending machines. The company operates more than 7,000 machines in California and more than 14,000 nationwide and maintains its water is safe.
"For the past 20 years, Glacier Water has been committed to providing safe, high-quality drinking water," read a statement released by the company Monday. "Our water vending machines start with federally regulated municipal water which then passes through a comprehensive seven-step process. To ensure the public's safety, we complete over 49,000 tests each year through independent third-party (Environmental Protection Agency)-certified laboratories."
Lea Brooks, a spokeswoman for the state Department of Health Services, said the agency will perform random tests on Glacier Water's machines as a result of the environmentalists' findings, but she said the water is still safe to drink. The water-vending machines face a tougher standard than tap water, Brooks said. To use the Glacier Water machines, which are often located at grocery or drug stores, consumers deposit money and fill their own jugs or bottles. The water, advertised as cleaner than water provided by utilities, typically costs more than tap water but less than pre-bottled water available in stores.
The two Bay Area environmental groups said they tested the machines, located in nine major counties around the state, for trihalomethanes, or THMs, chemicals that are a byproduct of treating water with chlorine. Drinking water is commonly treated with chlorine. In a third of the cases, the water exceeded the state standard for THMs of 10 parts per billion for "vended water," or water sold from machines, according to Bill Walker, West Coast vice president of the Environmental Working Group.
Studies suggest that exposure above that level can lead to low birth-weight babies and other health problems, Walker said. Water from about two-thirds of the machines also failed to meet Glacier Water's advertising claims that the company's filtering system scrubs out 97 percent of THMs, according to the lawsuit. "It's a question of consumer protection," Walker said. "We tested their machines to see if they're telling the truth and they're not." Water quality in the tested machines varied sharply by county, according to the groups' report.
In San Francisco County, only one out of 15 machines met the state standard, the report said. In Santa Clara County, all 15 tested machines hit the mark.

??? so sick of the idiots running this site. All I do is try to state objective things. Deleting my account. I don't trust you guys anymore to make logical decisions that could affect the security of my life.
A high rep member wrote me once:
I know exactly how he feels. And I don't have the time or the trust to deal with "misunderstandings".
If someone is going to be rude to me, and that precludes me from trying to help them, from trying to be good natured... well fuck that. goodbye. I guess no good deed of mine goes unpunished.

oh no...can the site possibly survive now???
I am using the 6/9 formula RO water pH 5.5 handwatering once a day. I started getting a few spots and some yellowing, so I bumped the pH 5.9. Now 3 days later, the problem seems to be getting worse. This is my 1st run with coco, so any advice is greatly appreciated. Here are some pics...

pics didn't show up.
yellowing between the veins on lower leaves? Sounds like a lack of Mg.

Too me. Mag is not the main problem there look more like calcium deficiency , which will cause the slight mag issues seen and the slight nitrogen deficiency I see as well. What ppm are you feeding? Do you have any cal/ mag you could foliar feed? I would try lowering the PH a little for better cal absorption , and maybe mixing in a little tap water if you have no source of cal.
