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 :)

Sorry I'm no help but was reading and looking and I have the exact same problem with one of mine with all those holes on leaves. I put it in a different spot this year outside so has to be bugs others are fine just weird. Also it's been super wet from rain so affecting health. Arber spray is good for prevention and treatment of every fungal and plant disease. PM and budrot also.

The small holes on leaves are bugs for sure but I can't say which ones. The tent is full of different ones. I am using some kind of yellow sticky things to catch them. Can say that the new growth has no holes so it helps.

Would you know why a random branch on a plant is getting yellow leaves while other branches are nice and green? Fungus? N def?
I am quite confused since the plants get fed regularly with apropriate ppm level and ph.

Never heard about Arber but I will chcek it out.
Noticed some PM aswell and other fungal leaves desease. Humidity is too damn high.

Good luck mate with this years harvest!

Looks like leafhoppers, lots of them in the lower canopy.
Last chance to spray pyrethrum couple times and get that under control.

Probably more stuff too, caterpillars aren't a big concern with no buds. When the pistils start forming it's time to keep up with Bt-k.

Never heard for pyrethrum or Bt-k. I will search for it online. As I said visually I have found no caterpillars.

Found pyrethrum spray on amazon but no bt-k, I will search some more. Definately good advice since I had caterpillar infestation last year on one of my plants and it got severely stunted and I had to harvest her mid flower.
Thank you dude.

You can buy bt spray by deadbug for caterpillars and the bud worms they leave. Comes in a spray bottle just shake and spray or Monterey bt for concentrate.

Look on the leaves undersides for pests. Some smaller than a speck of sand. A bright flashlight will make them move and become noticeable.

I have noticed some leafhoppers and in general.a lot of flies and different moths some white butterflys. But on the leaf underside I don't see much. Will start applying BT soon and some neem.

Does anyone know why am I getting some of the leaves yellow? Am I underfeeding them? It's wierd since I have also noticed a mild tip burn which could be over feeding....

When your into flower especially late no neem oil it will ruin your buds. Awful flavor and smell because it's a oil and spray in morning or night don't want direct sunlight to burn em.

The holes look similar to potato flea beetle damage that I get on my tomato and potato plants. Captain Jack's Dead Bug and diatomaceous earth is what I use to control them.

The light green color could be nitrogen deficiency caused by pH lockout.

Ph when I feed/water is at 6.5 always. What should I do?
