Defiency or excess ? need help from experts

Hello everyone,
I am engaged in cultivation in two tents, one measuring 3 meters x 3 meters and the other measuring 2.40 meters x 2.40 meters. I am trying to take care of approximately 60 plants in total. My powerful lights were burning the room and i add air condition and it goes well for not but I have noticed some nutrient deficiencies in some of my plants, but in order to avoid making any mistakes, I would like to seek help from my expert friends.
The plants are being grown with Biobiz All Mix soil, using 14-liter pots. I am also using Advanced Nutrients Micro Grow Bloom, Cal Mag, Piranha, and Tarantula nutrient supplements.
In general, the issue I face in my city is that tap water has a very high ppm (parts per million) content. The other day, the ppm level in my tap water was approximately 500 ppm. I believe that this high ppm is preventing me from providing the nutrients my plants need. That's why I've ordered a filtration system, and I believe that once I provide the appropriate nutrients with it, everything will improve.
What are your thoughts on this? Do you think these issues are due to a lack of nutrients, or could there be signs of toxicity?

My city tap is 7.6 - 7.8 ph / 345 ppm ( cali ) , i use it for my soil , hydro and coco and just adjusting feed and ph according to grow style.

Haven’t had to use “ special “ water.
Grass / cats / outside snd inside plants don’t care.

The reason you have issues is the multibottle approach to growing a plant. You would have been better off with grow / micro / bloom only.

All the other stuff is just fluff. Money grab nonsense.
You could just added a tablespoon of Dynomyco into top soil ( scratched in ) and watered . Only other issue would be ph buffering within your soil ( peat ) choice , as i am not familiar with that particular line. Most RTU ( ready to use ) bagged soil medium will have ph buffers in it ( oyster shell , lime , etc. ) as grow moves forward, buffering can wane but easily recharged by adding s few cups of fresh medium on top ( topdressing ) and watering in.

Its stupid simple.

You will find buying “ lines “ ( bottles ) of some cartoon labeled crap is not necessary- matter of fact - you could stop all and get a bag of roots organic terp tea grow / bloom and run a tablespoon once a week.
( dry fertilizer ) ( soil. )

or Gh maxibloom ( soil or hydro )

again simple.

It seems like you may have bitten off more than you are able to chew. Don’t feel discouraged, scrap the plants that seem too far gone. Take what remains and put them in large pots. Top them & let them take up more space individually. You won’t even notice the other plants are gone.
You’ve gone this far. No need to let something stop your forward motion.

To me the plants look to be over/under watered. Hard to tell which. If feeding by the plants age, you should be giving them 2ml per liter of water for a full feed. Give the additives once a week.
If heat & humidity are too high, try exhausting outside.

"Thank you for your responses. After fertilizing my two pots today, when I checked the ppm reading from the runoff, it was around 2300, and I thought there might be an excess of nutrients, considering that the plant couldn't take up the previous nutrients I provided. Therefore, I conducted a nutrient flush today with pH 7.0 without any additional fertilizers. The yellowing in the plant is progressing. Do you also think it doesn't resemble a magnesium deficiency as seen in this picture?"

I don't think I saw it, but you mentioned the PPM of your starting water is 500 (is that on the 500 or 700 scale?), but what is the PPM after you mix your nutes?

The leaves that are completely yellow are deficient in nitrogen. The leaves that are showing yellowing between the veins (interveinal chlorosis) are deficient in magnesium.

I think its possible the 500ppm starting water might be part of the issue, thats pretty high. Its only happened to me at one place I've grown, but I had one house that the water was 4 hundred somthing ppm and plants were growing screwy. When I switched to better water it solved the issue completely.

I would say from the looks of the leaves that you were probably over feeding and are dealing with lockout now. The flush you did might help, or it might stall them even more.

What ppm or EC levels have you been feeding at?

Dear friend, I completely agree with you regarding the high ppm issue. I, too, noticed this a bit late. I was giving the nutrients but girls doesnt accept to use it. It seems that my plants have responded positively to cleaning with pH 7.0 purified water from the 1 day ago . I believe the excess of certain nutrients might be causing a blockage in the intake of nitrogen, magnesium, and potassium.
Anyway, for now, I can see the nutrient deficiency, but I can also see improvements. I think I'll observe with fertilizer supplementation after another flush. Their lifespan is only two more months, and they need water every two days.

I have no idea if it's a high ppm issue because you have not stated what the EC or PPM of your tap + nutrients combined is that you are feeding to your plants.

Well I just looked into the Bio Bizz All Mix, and its specifically says its a high EC mix. So if there is a mystery 500ppm in the tap, PLUS the advanced nutrients, plus the high EC soil, I'm sure its probably super high ppms, and a totally random nutrient profile.

Do you get run off when you water normally? What are ppm or EC are you feeding them at?

Hello my friend, apologies for the delayed response; I was dealing with several issues. In the irrigation section, I had a partner who seemed to be causing some problems, but now that I've automated everything, things are going quite well. The filtered water worked well for me. I performed a clean water process once and then irrigated again with a solution that reduces salt content. After that, I started providing nutrients. Managing about 60 to now 70 plants and cleaning the wastewater beneath them was quite challenging, so I added four pools inside the tent.

Below, you can see half of my flowers crammed into a room. They're possibly about 50 days old,, but they don't look too bad. Yesterday, the tent's central poles broke due to negative pressure, and everything fell down. Luckily, I was able to repair it quickly, and there was no damage.
For automatic irrigation, I use soil sensors from the Sonoff brand, referring to about 4-5 of them to draw water from my 350-liter tank for the 70 plants. When the sensors detect that the humidity has dropped below the level I set, the smart plug activates automatic irrigation. It's becoming a better system day by day. Hopefully, I can share even better pictures soon.
