I bought 4.0/7.0 calibration solution today and it seems my pH pen wasn't off by that much (at least by my standards which are pretty low).
same picture as above(just on imgur):
On the left is what it read when I dipped it into the 7.0 solution.
Off by .13. It could have been more accurate @ that range rather than the 5-6 range.
The 4.01 reading was what I got after I clicked "CAL" on the pen while it was in the 7.0 solution, but I still calibrated it again while in the 4.0 solution.
I probably should have tested what it read in the 4.0 solution without any calibration, but I was ready as all hell to get this thing calibrated asap. I now regret this.
So I'm kind of worried by this as it may have not been off by that much to cause a pH problem.
So it may be other factors as to why the pH is off within the medium.
I have never kept this pen in any type of solution at all to keep it moist and I've been doing this for about a year and a half (this is my second grow).
So it seems I've had some good luck with this pen in regards to that. I have always cleaned it and babied it though, for what it's worth. Only used tap water on it as I heard distilled can leech ions from within the electrode, but I did test the pH of distilled water in this thread (only time it has touched distilled water).
I bought their(ketotek) humidity controller and it didn't go so well: https://www.rollitup.org/t/will-my-humidifier-work-with-this-humidity-controller-voltage-question.1005546/

I'll give it everyday feedings to run off. If I'm exacerbating some type of root issue by doing this, then this is a good learning lesson. I will still have something to show for it unless something develops on the bud sites.

More on par with the 6.0 color pic that I took. Leads me to believe the pen might have been off around .3-5ish?
Probably not enough to cause what I'm going through.
I'm still a noob so I don't really know how far I can be off, but I do also figure 5.8-6.2 is easy to hit and a good range to be within.
Hopefully all is good now. I figure off by 1 won't screw me like what I'm currently dealing with.
Beginning to think this might be root related. Not sure what all can cause lockouts.
If the pH is fine then the only other thing I can think of is salt build up or something in the roots like algae/mold/rot to the point where nutrient transfer is being disrupted.

I'm going to daily watering, so hopefully that won't make the situation worse. Just doing hail mary shit now.
My first time growing in a 1 gal pot. Issues come on really fast it seems.

I will stop with the calcium ascorbate in next feedings. I'm aware of others using this to dechlorinate their water with no ill experiences(from what I can recall). In my first grow I used regular ascorbic acid(pure vitamin c), but it dropped my pH very low (in my nutrient solution) to the point where it was a pain to deal with. Never had an issue like this in that grow. If it's indeed the culprit, then it's causing some type of reaction with the bud explosion as this was the only new thing being used (but I have been using it(BE) for a few weeks now (may have took a while to build up a deficiency/lockout of some sort)). I've already dropped BE (since last feeding). I'm just trying to salvage what I can and not maximize anything @ this point.I would do this: quit adding vitamine C, take your tap (if you are aware of chlorine let it sit for a day but it wont help anyway) mix your base nutrients in it (K:Ca:Mg 4:2:1) around 1,1EC, be carefull of too much nitrogen and measure its pH by drops. I did it like this, fill your cap till 2cm, add drops, shake and put it on the white paper. Look at it from the top and the colour of the bottom is your pH. Colour 5,5-6,5 range your are fine do not mess with it and feed untill you get same EC runoff. You may need a lot of water. Than buy a legit pH pen and start to treat it like coco. GL!

I'm now feeding 5.8ish. Not 5.9. Any specific reasoning behind the +.1 pH and not the 5.8 that is recommended by some?Your ph is too high.... a bet your run off is way higher than 6.2. You need to feed at exactly 5.9 and you need to feed til run off every day otherwise you'll get this issue
Edit.... didn't read the whole post lol... bit late... but I was right!....
Keep feeding every day til run off to keep that ph down....

I haven't been paying much attention. I did lift the pot like 3 feedings ago and it felt light. Other than that I only poked my finger down twice during veg and it was slightly damp on both occasions. I still watered it because it was 3-4 days before the last feeding. I only amped up watering during the last week or so of veg and throughout flowering (to every 2nd day). I've only had a few issues here and there during veg (as shown below).How dry is your medium when you feed on the second day?

The 5.8 reading in my last post looks slightly darker than the calibrated 5.8 one below.I think the 5.8 is too high on the meter, going by the color of the fluid (at most 5.5 would be my guess).
All the pictures you've posted show a fluid that is going into the orange, and that would be below 6.0 already according to the chart.
There's no way around it, you'll have to get calibration solution and use that to get your meter back on track.
Also, this reference with photos of actual vials is great. It also shows you really do not need 2 drops per vial, it only makes the color slighly more intense.
For me, the "6.0 yellow" has always been very obvious to recognize.
"Piss green" is actually a very good reference for 6.5
At the end of the day, how accurate do you have to be? If, say, 5.8-6.2 is good enough, that means you will have to get a clear "yellow" with not much orange or green in it. It's possible for me to recognize that, but for somebody with some form of color blindness it might be a problem. These people should not use test kits or test strips in any case, though.
