How to cure a sick plant?

Hello to everyone reading this thread!

My name is Roy.
I have been growing weed outdoors for ten years now. Had some good years and some not. Every year is a learning process and also brings new problems.
Now this year is wierd weather wise. From April till June it was quite cold with lots of rain.
It got hot in July 35°C but there was hail and rain and the air is realy humid.

My setup... I have a small outdoor growing tent 2.5x4x2m with 4 plants in 25 L fabric pots.
BioBizz light mix soil with added michoryza and some other good stuff.

I gave them GuerilaGrow(BioTabs Nl) slow release tablets. I didn't read the instructions well so I didn't add enough of the tablets to the soil. Noticed some nitrogen deficiency and started to add Orgatrex (5/1/5).

From start it helped but one of the plants started to get sick. Simptoms yellow leaves with violet stems. Looks droopy with some of the smaller leaves starting to twist. I have flushed it and gave her fresh nutes but somehow nothing has changed. Some of the foliage is nice and green and perked up some of it is droopy and shitty like there is two different plants in one.
I am using tap water roughly 6.5ph feeding them between 1000 to 1200 ppm every second/third day depends on how much time I have.

I had same issues with one plant last year no matter what I did the plant did not respond and in the end whole leaves turned brittle and brown like it had some kind of a fungal infection.

Other three plants look decent although some of the leaves are getting yellow like it would be nitrogen def but I have no idea why since they get fed and wathered regularly. Noticed all of them have small holes on leaves like they got eaten up by a pest unknown to me. Visually I have scanned for caterpillars but found none.

Picturs in attachements. If some of you fine gents could point me in to a right direction it would be appreciated.
Thak you :)
