I think that the plant is going well.However what kind of problem is this burn on the leaves. Also i think that i found why there are yellow leaves on the bottom of some plants.
I noticed that some plants are drinking they nutrient solution faster than others and then they start drawing nutrients from the leaves.So the yellowing of the leaves is connected with drier soil. Now i water all of then more often.
They look good now. Trim em up really good, aerate your pots somehow, maybe a small stick, then let them pots dry up a little. Using old soil is not a bad idea, but you cannot use ferts over and over without some weathering of the soil. Back off on nutes and use castings for a couple weeks.

those two leaves are burned, it is light burn more than likely.

When the yellowing and spotting starts at the bottom of the plant, it's nitrogen.
If it starts at the top of the plant, you need Zinc.
It could also be light stress which is different from heat stress.

Raise your light about 4 inches and see what happens.

Hi, so yesterday i saw them for first time since 3 days and made a feed nutrition with ppm - 1300 and i watered some of them. At first i didnt saw that there is problen because i was very tired and high. But then I saw that some of them have dont look good. Since that moment I stoped pouring feedilng solution but used clean water for most of them. I have rised the lamp . So before the highest buds were at 45-50cm . As now they are at around 65cm distance. I consider to lst some of the branches but it will be probably on monday . I work 2 jobs and i just dont have a lot of time and energy to take out all plants amd to take care of them.
Today after i got from work in the evening i saw them and they are not in very healthy condition.
Now i will show a few photos of 2 of my plants which are more sick.
As you can see they are lollipoped and defolated on bottom.
Guys give me advices what to to in order to improve them. I stop feeding with fertilizers.

ok your main problem that started this was watering too frequently the damage is there to see.. so i see the bags sitting on the floor? is it a cold floor? you say clean up spilled water? those bags sitting in that water while your gone? you know your temp and humidity for lights on and off?

Hi, the fabric pots are in plastic trays. Before i had some plastic trays under pots which were smaller and when i feeded them the water was spillin on the floor of tent. Since a couple days i fixed that issue. And its not cold floor. Its on the second floor of the house
Temp lights on- 26-28c Humidity- 55%
Temp Lights off- - 17-20c Humidity 65%
Also today i will place a small dehumidifier in which you use tablets to draw the moisutre and its collected.
Tell me what can i do in order to save as much as much as possibe.
Is there any product that can help my roots?

Hi,I watered them every few days . The problem is that because i used bad soil there are some nutrient defiency and i watered more to combat that but then the roots got sick. Also i watered all plants ot once so some of them didnt had dry soil so this is also and problem.
I hope to manage to save most of the plants as not all of them have serious issues.
Is it a good idea to use that product which can help the roots

you could give that go it wouldn’t hurt them, but only do it when the plants are dry ish and need water, the watering too frequently is what’s causing your issues, get your watering on track and hopefully it gets healthy enough for a good finish.

These 2 plants are the worse than others but overall all plants looking better than week ago. Now i feed them with only plain water but too much at once.
I would like to ask if its a good idea to bend the tallest branches .
Atm the closest branch is 55-60cm from lamp. The farthest branch is 80cm from lamp.

maybe there's been a number of different problems come up with this grow. I would take the sickest looking plant and re-pot it just to see if that helps, can check out the roots while doing it. One container looks like its been wet forever and has a lot of build up on the outside

Peroxide. Remove most of it and disinfect with Peroxide. Sulphur application on the soil. Maybe a fungicide spray.

those burnt or light coloured leaf edges, the tops curl down, etc signs of overwatering, the fungas? around the stem from too wet and air too moist.. i’d spray some h2o2 on it..
