In need of HELP AUTOFLOWERS DWC

Im a new grower in DWC. I know enough to have gotten this far but looking at pics and videos i feel im behind. I have 4 plants in a 4x4 tent. See pics for setup. What i need to know is why with roots in the water my PPM is going anywhere? Every bucket is at the same level as they started if not a little higher. A\C keeps temps perfect.
Tent.
19.8 Celsius and 41% humidity= Low
23.4 Celsius and 62% humidity= High
These numbers have been the same since start. Maybe 1 to 2 degree off at times.

Buckets Water Temp.
Between 20 Celsius and 22 Celsius
And these numbers are also pretty steady.

PPM FOR MAZZAR
350 PPM - hasnt moved since nutes where introduced.

PPM FOR NYCD
400 PPM - same hasnt moved.

PPM FOR NARCO PURP
380PPM - same issue

PPM FOR NARCO PURP 2
410 PPM - number hasnt moved but this has really came along way. Compared to how it started.

I also Ph everything starting at 5.0 now they all stay around 6.2 to 6.5 if i Ph down it always goes back between these numbers. Is that good or bad?


I just need someone to talk with and let me know am i on the right track. Last pic is of T5 4ft 6 bulb. Do my plants look sick? The spots that stand out u will see can someone let me know if i have a problem. Am i doing anything wrong. Ive spent alot of time reading and youtubing but i need help from people who are actually in my shoes. HELP PLEASE.

They look good to me, ppm levels look ok. Keep ph around 5.8-6.0 in veg, they'll probably start eating more in that range. Raise it to around 6.0-6.2 in early flower, try to keep it around 6.2-6.4 the last couple weeks of flower. Run veg nutes through the first week or two of flower to maximize yields.

The fact you are phing down, and it keeps rising means they are eating and you're around the right strength nutes.

Some general rules.
If EC goes up and PH goes down, they need less nutes
If EC is stable, but ph goes down, they need slightly less nutes
If EC goes down and PH goes up, they need more nutes.
If EC is stable and PH goes up, you're just about right.
You're trying to get EC to stay stable, or drop slightly, while ph stays stable or slightly rises.

Thanks. The 7th will be one month for me. My girls are showing there sex. At which point should i start flowering nutes and advance nutes. I have Big Bug, Bud Candy, and Overdrive. I read online that once u see flowers start to form you should still do veg nutes for another week before starting flowering. I hope im not being to annoying. I have a ton of questions if your willing to answer them weedfreak78.

I run my veg nutes until the flowering stretch stops, usually about 2 weeks after flower sites show. This will add a week or so to the finish time, but I've noticed drastically increased yields doing this. If you're on a tight schedule, switch to flowering nutes when you see flower sites, this keeps finishing times close to the what breeder says, but withe less yield.

I have all the time in the world. This is my first grow but im a heavy smoker so i want to get the biggest and strongest buds possible. From looking at my girls would you say they are starting to flower or should they still b n veg? I dont want to start running flowering nutes to early. Ive invested alot of time and money into this grow. I only want to get bigger. I also have questions about air quality and venting.
