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!

No. You need to manage the pH. Measure it once you've made your mix, then correct it.

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

[GhettoStyle]

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.

[Bluey]

Not much here. At most 0.25 but often only 0.1

[Bluey]

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, could you please let me know up to what level (EC) or (PPM) you are adding cal-magnesium?
I am using tap water with an (EC) of 0.2
so what level should I add cal-magnesium to it?

[GhettoStyle]

I measure it 1-2 times a day! pH metr Sanxin

I don't quite understand your question about using a hydroponic system???!!!!
and why do you recommend such a high pH?
I use an aquarium cooler!

[Bluey]

How are you measuring pH and with what and how often? Pic of the pH pen if your using one please GhettoStyle

I agree with Bluey. While some may be able to master DWC from the beginning, most new growers don't take the time to learn the intricacies of growing in DWC. They aren't used to being responsible for EVERYTHING the plant needs.

I would agree that starting in soil is the best way to understand the biological processes that happen along with having the time to correct whatever mistakes new growers make.

I started in hydro because I heard it was the fastest, cleanest and most productive way to grow weed. I was like most newbs and jumped into it thinking it would be easy having grown vegetables outdoors. I wasn't prepared for all that went into it and failed. In those days the only info source there was was other growers. No internet forums. I decided to try again but outdoors. I had more success and continued but learned a lot about the bio processes that happen rather than just water and watch them grow. My outdoor grows got better and when I moved up to NorCal they got exponentially better having a few of the hippies I worked for take me under their wing and teach me what they had learned over the decades.

I would contribute that DWC or hydro in general is perhaps the most advanced way to grow. The results can be excellent for experienced people no question, but when I see people say “ it’s my first grow and I’m doing DWC” I just shake my head.

I have never used any other method,the reasons are many, due to the location I need a short winter growing cycle plus I have very limited space, soil just wouldn't cut it for me.

Hydroponics is an excellent and easy way to grow, but needs to be monitored daily as things can go very wrong quickly if not caught in time.

DLI 15
temp 25C
res 21C
EC 0.7-0.8
pH 5.7-5.9

Are you using some sort of hydroponic system?

If so I would bring the pH down a tad closer to 6.5.

Likewise how are you chilling your nutrients, do you have a good flow rate from reservoir to tank, if not your tank temperatures could be higher compared to the reservoir, the temps if too high which can retard nutrient uptake plus high tank temps can result in root rot.

I found a temp around 73F is ideal.

I don't like growing in the soil! in my opinion DWC is a more advanced and cleaner way.
