It seems I have offended your fragile ego by not agreeing with your solution to the issue I had because it was wrong.
There is no shame in being wrong, and I appreciated your suggestions to the issue.
I do however take issue when someone who thinks they are the "end all", "know all", fountain of irrefutable knowledge on cannabis cultivation
can't accept actual results contrary to their opinion.

Hey thats you not me and reguardless i was asking to stay in touch with this over the future runs as if it was it would be even more obvious then.

Its not a know it all attitudecbut im not afraid to discuss plus on somethings its not that im right its that thats the right answer and its not my fault there is a lot of bad info on jarring wet buds and putting thermometers under lights on this board.

Also wondering why your promix would be vastly different to mine with ph, they are limed or of peat that keeps ph sweet not an acidic one. Even peat itself takes some time to degrade and produce this acidity after being horticulturally prepared.

So you had a problem and solved it pretty quick but thats the end of discussion... great :-)

i've been growing in pro-mix lately and i like to vary my pH from 6.0-6.5... if i maintain low ph i see ca/mg def, if i maintain higher pH i get weird curled and bunchy new growth (maybe boron def)

if i alternate between 6.0 and 6.5 everything stays nice and pretty. also, i feed-water-feed-water to avoid burnt tips.

All our garden centers here close at the end of Oct so I had to reuse a lot of ProMix from last summer, so It's not virgin medium which
might be partially to blame. All I know is I have 20 clones and 20 adult plants that look great just from keeping my PH no higher than 6.0

I have used pro-mix (organic herb & vegetable), on its own entirely, or mixed with extra perlite/worm castings, one i mixed with maybe 20% coco..i have used the HP version as well, again on its own or mixed together, i have been reusing the same 150+ litres for over 2 years now, and the first year i had issues, always the same thing, around the same time, i always ph'd around 6.5..never under 6.3, or above 6.8.
Finally last year i started doing more research as it was very annoying to run into the same issue over and over. I finally started lowering my ph's, and since then, no issues at all, plants grow perfectly. My ph now is kept between 6.0-6.3...on the rare occasion, it may get to 5.8-5.9 going in, but no issues. For what it's worth...pro-mix recommends ph be kept between 5.8-6.3. As someone above mentioned though...the alkalinity of your water is far more important than its ph!

Damn im blessed with low alkilinity from the tap, our tap water is actually tasty and most quite like it.

So recently i got a letter in the post saying they are changing to a state of the art facility and the water us going to taste more of chlorine this month because of it.

The letter ends with perfectly normal and fine - yay more chlorine for my plants hmmmm :-)

Chlorine stinks doesn't it? My home runs on rain water and if im staying at a Hotel and have a shower, I feel like I need another shower...

Been watching this thread and sitting on my hands to watch answers....

I see you found your answer.....Re used is likely at the base of the issue...

Keep in mind as Pat breaks down, it becomes more acidic.

Now then. growing in any soil less media is considered a hydroponic method of growing. Like RockWool, Coco, Hydroton or any hydro media....General rule of thumb is run pH between 5.8 to 6.2

This is listed in every cannabis growing book around, as such...

As to those who may want to come back and start talking about how "they" use 6.5 and and such.....It's your water..... If you used neutral water (RO).....added a buffer and your feed.....pH'ed to over 6.3 and held that.. N def and other fun things would happen.

6.5-6.7 i sometimes go 6.3 but nothing lower/... only green happy plants! i think running that low will give you problems in the long haul!.. peat is acidic just my opinion.

ProMix is already ph'd neutral right out of the bag.

Yes, right out of the bag they are. Unfortunately peat breaks down causing an acidic reaction in the soil. Lowers the pH over time. Most blends don't have enough lime or buffers to last a whole grow. If you don't add it or pH your water accordingly you will run into issues. Usually pH'ing the water isn't enough in the end.

If they added enough then they couldn't sell you the lime by itself as well as a production a cost thing.

Peat also holds onto salts very well. Hence someone mentioned it likes to be flushed or watered to a decent run off.

Ph was the issue for sure but salt build up goes hand in hand with pH. Salt build up will cause pH problems. Build up of certain elements will contribute to the soil being acidic or alkaline.

Also a fact brother!

I missed the reused media as well.

Definitely a factor.
