If using dwc you should let it rise to 6.5 or even a tad more before correcting it.
I wanted a photo of your pen not one from the internet but anyway.
I'm not familiar with that brand but their top of the line pen appears to be a rip off of the Apera PH60....which is a lab quality pen..its what a lot of us use where pH is critical. Available at the Amazon apera shop.
Do you calibrate it?

Dear friends, I am at a loss as to what to do. I don't understand what happened! From the start, when I connected the system, the reading was 200 ppm. It was tap water with a concentration of 100 ppm + 100 ppm CAL-MAG.
Then, I added an extra fertilizer 100 ppm, and it read 300 ppm total! But the next day, added more fertilizer +100 ppm. The next day, the problem with the leaves started.

Friends, if the pH drops, then you need to raise the EC​?

Yes, I noticed that the pH drops after adding nuts!
but I have a slightly different situation! after adding nuts, I raise the pH to 6.0 and then after a day the pH drops to 5.4-5.3 pH! The solution level is difficult to track, but it seems to be unchanged, as well as ppm, too, unchanged!

Do you have an air stone in your reservoir?
If you don't add one, then set pH to 5.8 and correct it every 24hrs. It will rise not fall.
With a falling or rising pH you should set it so it moves through a range at ideally around 5.8 to 6.5.
It's important to have an airstone to keep dissolved gasses high in the solution.

I have an airstone! This is the main thing in DWC! I thought the pH was dropping because there weren't enough nuts!

I raised the EC to 1.1 545ppm
I change solution every week

Does the BAC bottle say how much to use? (Their website has almost no useful product info)

Some questions for you:
1) What are you using for the DWC set-up? (5 gallon pails or something else?)
2) Are you using the full compliment of the Canna Aqua nutrients? Or only some of the products?
3) Are you following their feed guidelines? (See the image i attached from their website)
4) As a new grower, avoid adding nutes between water changes. Plants absorb nutrients at different ratios, so adding more nutes might provide some of the nutrients it’s looking for, but also risk creating too high a concentration in other nutrients.
I’m a DWC guy with a few years experience. Even now, if i have a nutrient issue that has me struggling to understand the cause of the problems, i do a full water change instead of cheating the nutes between water changes. Nutrients are cheap when a plant is that small.
So, to get on the path to getting that plant healthy:
1) do a full water change and follow the Canna Aqua feed schedule. From looking at that plant, your re still in the “Vegatative Phase I†of their feed schedule. (Line 2 of their guide).
2) Add your CalMag additive following the directions on the product.

Yes, I use 5 gallon pots! The other day I raised the pm from 300 to 550 ppm and now the plant has stopped growing and the pH has started to drop from 6.0 to 5.2-5.3 every day! in my opinion, the feeding schedules from the manufacturer are very high! since it says 3-5 days and 520ppm in the table, these are big values! so I tried to make 550 ppm at week 3, so the plant stopped growing and the pH began to drop every day.

it looks like I killed the plant so badly that it won't recover now((​
initially, it was on water with calcium and magnesium 200 ppm and then I added nuts and made 300 ppm and then after a couple of days I made 400 ppm and the first symptoms of necrosis appeared​
here is a photo of how the plant looks now! I cut off the bottom leaves as they are almost completely dry!​
I also read about deficits on the forum! and I don't understand NPK mobile substances, so the symptoms will always go from the bottom up! Magnesium is also mobile! but calcium and sulfur are not mobile and the symptoms start from the top at a new growth! so the photos that I took today show that chlorosis is present on the newest leaves!!!​

That's my previous question! I was creating a topic on the forum when the top leaves were swirling, but I figured it was because of the light, high temperature and low humidity!​

I use 5 gallon buckets and my nute strength for a plant that age would be around 1200ppm (500 scale). I use a different brand from you, but for most DWC nutes, the measurable ppm should be the same.
She’s starving. Use a clean bucket, or make sure her bucket is clean inside….make a fresh batch of water and nutes for her following the feed schedule i posted to you earlier. Make sure the water level in the bucket is just below the basket, maybe a 1/2†or so. Make sure your airstone is pumping out lots of bubbles.
The sooner you get it done, the sooner she recovers.
And pluck off those large leaves that are yellow and dead. The plant is wasting energy trying to heal those leaves. Getting rid of those leaves will help the plant put energy where it’s needed.
