BIOBIZZ. Is this too much supplements? NOT nutrients (N,P,K)

Are the droopy ones smaller than the others? Probably are, if they had been droopy all the time. My plants got better around week 5 and They are okay since then. I did careful observation to solve this. Firstly I discovered that my lights were too strong and they were always suffering in the end of day cycle until I fix it and they got better. Now they look like praying both day and night and getting dry properly in every 3 days.
First check the lights second point is wait until the pots are really light to saturate again. I had sleepless nights last week just to be able to observe this.
Please post if you have pictures.

my plants look like this end of week 7

Thanks.

Here we go, this will be my "cannabis infirmary" test run
I will try to be as concise as I can.
3x3 tent, 240w kingbrite led and mars ts1000 - 150w, 3 gallons (10litres) pots.BIOBIZZ nutes and RO water. (80% RO +20% tap)
Ph of water about 6.8-7
Autoflowers from fastbuds

I am posting 2 pictures of the same plant - day 41.
Envrionment has been good, I wont go into details but I have been following VPD and temperature ads humidity both are in good range.

This DROOPINESS has happened to 6/8 plants. (4/4 last grow, dumped them on day 30.And 2 of 4 this grow) The droopiness starts from top. Days 20-23 top was droopy but bottom fan leaves were perking up.

I have tried many different watering methods
a) 1pot was presoaked with 2 litres and rootjuice
b) 1 pot was presoaked with 1 litre
c) 2 pots werent presoaked and I used this watering method - https://www.420magazine.com/community/threads/the-proper-way-to-water-a-seedling-in-a-large-final-container.478973/

Timeline:
1) I gave all of the plants their first big watering on aboiut day 14-15. Each got 1.5-2 liters of water. NO NUTES. Before day 14 presoaked pots received less water. non soaked pots a bit more.
2) 2nd watering on day 19-20. 25% nutes.
After 2nd watering plants start to droop immediately, they perk up 24 hours later for a day and then droop again.

3) I waited longer for 3rd watering - 7 days , because I thought the droop is caused by overwatering... The problem is they start to droop BEFORE it is dry. ALSO, there was no point waiting longer than 7 days for 3rd watering, because the pots only lost about 50 grams of weight per day AFTER day 7, while before that they were drinking about 400-500ml per day.

4)I flushed this plant. 10 days have passed. It still looks the same regarding the droop. I have watered 1x after the flush. (It dried for 5-6 days, drooping all the time)


Conclusion:
1) I made sure soil isnt too loose or too packed
2) Environment is good and water ph is about 7
3) I doubt its root bound, 3 gal pot for autoflowers should be enough. Even then, last grow 4/4 plants drooped and thats unlikely..
4) Different watering tehcniques were used, but plants all droop the same.

I have no idea why they start drooping after 3rd week....
I am doing something wrong, but I also try to follow all variables. I weigh the pots every day to see when they stop drinking etc.

Possible answer:

1)From days 20-25 there was some heavy TWISTING in top growth - that could mean a PH problem...
BUT - is it really likely that I mssed up the soil PH in only 3 weeks? I always tested the ph of the water/nutes I gave the plant.

Hey, sorry for late answer. I didn't really get what's the problem often times flushing does not solve the problem when growing with organics. Flushing is the solution for many situations when growing but doesn't work with organics. First of all If you pour too much water to the pot you will wash out the microbial life as well then your plant will not be able to take up almost any nutrient. I am also having difficulties this week and can't figure out why. It's really hard. I want to switch back to mineral nutrients just for ease of use sometimes.
your plants look tall maybe the light is the problem it could be too much for the upper part.

Yeah ,I dont know whats wrong either.
I am assuming its me who is doing something wrong.
And I just dont know what.
12/12 plants have failed. (3different grows)
after first 4 failed, I approached the rest "scientifically".
I have separated them in groups and watered/fed differently.
I have provided weaker/stronger lighting
VPD, DLI have been in check. Water is RO (usually mix in 20% tap)

Still-even with extra careful approach, 12/12plants are showing deficiencies starting from day 20-25 and I cant get rid of them.


I have chosen to quit Biobizz (BTW their calmag requirements are seemingly 3-5x lower than in real life, VERY unproffesional) , quit organics and I have already ordered 15 litre autopot system with 47 litr reservoir and synthetic nutes .Now my plants will grow/feed automatically (autopots use gravity) and with very little input from me. If this fails,I will be convinced we live in a simulation
