Bubbleponics: pH query

[Panos]

This is my second grow. First attempt was in soil which ended in disaster.
Now now set up a bubbleponics DWC tent (specs below).
I am into the middle of the third week,veg state, and the plants have been looking great. Will try to post a pix but this has been giving me problems.
Using GH Flora series, magical, and hydro.
I mix a 10 gallon batch at 50%: In teaspoons: magi=1;hydro=2;micro=4;gro=61/4;bloom=2.
Yes, I add the magi first, let it rest for a few minutes, then hydro and the rest,etc.
**I then carefully adjust the pH to about 5.8**
This is what I've been replenishing my tank with since the start. [According to GWE site this nuti mix can last for about 2 weeks.]
However, on my last water replenishment noticed the following:
**the pH of the water taken out of the tank was around 10.4--I had just been throwing this water out.
So I tested the water in my grow tank and that was also pH 10.3circa.
I am puzzled: The plants look great. Is this something to be concerned about? If so, what is the best way to fix it?
OK now lets see if I can add a picture.



Current grow:
Nirvana White Widow feminized. 2 seeds.
DWC, 10 gallon tank
400W HID
GH Flora Series, Magical, Hydrozon.

Thanks in advance people,

Hi Panos, They look lovely, and let's get em to stay that way!!!

First question: Are you sure your pH pen is accurate?

2. How often do you check the pH? I grow DWC also and I check pH religiously every morning.

3. Are you checking the pH of the nute mix that you allow to stand for a while? I don't pre-mix; I change my reservoir once a week and I just add pH'd water in between if it's necessary. (Just me: that's how I do it.)

[Panos]

I have calibrated my pH pen.
I only check and correct the pH when I mix up a batch of nutriment solution.
I only have just started (Aug 20) to check the pH in the tank. I see this may be a mistake and should check it daily. I just assumed that when I mix a batch and fix the pH, it would stay that way...
So I assume that I can correct the pH for the water currently in the tank and from now on check the tank's pH daily? And check the pH of any pre-mix I'm adding each time.
Do I have this right?
Also added a post with a picture of the current state of the roots. [Still not sure of what i'm doing with pictures but hope this will clear up without too many hassles.]
Thanks for your input.

If the ph is 10.4 id say you need to correct it pretty much asap youd need the range between 5.6 and 6.3 thats where i allow my water to stay even though where i live sucks and some how my water does what yours does it climbs high as hell in a short bit of time i have to correct my ph in my system every 12 hpurs give or take ill lower it to 5.6 and 12 hours later itll be somewhere between 6.3 and 7.1 every damn day lmao idk how because every body says they have to worry about there water ph going down not up but for some reason mine goes ☝ ever few hours

How long does it take for the solution to get from 5.8 to 10 ? How do the roots look ?

[Panos]

Hard to answer exactly. I just noticed this situation.
Posted picture of the current state of the roots.

Here is a picture of the roots as of Aug. 18.

Panos, the pictures didn't show up. You may have to re-size them and make them smaller in order to post them.

If your water is really crappy, you might consider getting one of those portable RO systems for your reservoir water. dontknownuttin swears by his RO system.

My Ph has been stable since I started using an RO water system unless there is problems with pathogens like root rot or algae growth ect. I am not running DWC but in my constant drip recirc. hydro system my Ph does naturally rise slowly from a starting point of 5.5 to around 6.0 to 6.2 in about a week. I also use enzymes to help keep my nutrient solution clean also water temp around 68 and lots of air being pumped into the nutrient solution.

During res change I PH test the water after adding my hydroguard, GH trio, cal-mag sup (unecessary but I bought t so may as well use it) and terpinator supplement.

after nutes my water ranges about 6.6-6.8

For some reason my ph down is really effective at .5 ml/gal

that gets me down to about 5.7-5.9.

thats all I do

I don't check the ph in the res again unless my leaves show problems. I top off the reservoirs mid week (tonight) with plain water ph'd to around 6.0 even. (I use my leftover water to refill my foliar spray bottle.
