Too much worm castings in Autoflowers

I used a little to much worm humus on soil mix and I am getting N toxicity using just 0ppm water. Can you flush out the worm casting nutrients?
A week ago I flushed a plant and runoff came at 1200ppm, yesterday same plant on first runoff I got 1600, after 8l of water 1300 ppm. They are pre flowering and I don't want black plants :(

Pictures of the plant would help a lot. We'd also have to know what kind of soil mix you're using and any other fertilizer your giving them. I find checking run off ppm in soil to be of little help. Especially if it's a living soil. A slurry test for ph if needed or just watching the leaves and plant condition works out better for me. It's too easy to get caught up chasing numbers with runoff and often leads to lockouts from over watering and ph fluctuations.
 

My journal... ph is low... @4.5-5 on runoff
Water ppm 0, just water and 0.1ml/l TA root juice. Most of em got only water, some got 100ppm feed....
 
That's pretty low ph, but again when it's the runoff you're testing it has a lot of variation. Depending on the plants health, watering habits and what stage of growth it's in that number can be close to root zone ph or it can be a good bit off. If it really is that low you would want to get it up into the 6-6.5 stage roughly.
 
Ive never had an issue with overusing worm castings. I ditched the measuring cups years ago, my plants all get heaping handfuls of it basically whenever i feel like adding more.

Are you using fresh castings or some hardware store bagged stuff thats been sitting for who-knows-how long?
whats the NPK rating?

Biobizz Worm Humus. Don't know much about it...
What can I do... I can't make my own soil, I don't find much good shit in shops.
 
Plants don't look stressed. You're doing a good job.

You should ignite some cannabis and inhale the fumes, before you make your plants feel like there's something wrong with them. :bigjoint:

are you paranoid to have things shipped to you lol? I dont bother with "shops"
I get my castings from worm farmers. Farm fresh > everything else

it seems like you are chasing your tail a bit with all this flushing and runoff business. Its pretty common to kill them with attention trying to get all these numbers "perfect". At the end of the day its a plant, they dont need a ton to be okay, and they definitely look okay.

And that is what I don't want to do. Over think stuff.

How should I water them in future? Should I add nutrients? I use Terra Aquatica. If so should I give normal feed or lower because of the Worm Castings?

What does this blue edges mean?
Maybe they are underfed since I just flushed and didn't use any nutrients?

I have always heard that worm castings should not exceed 20% of your soil mix. This advice is from a worm castings farmer. Hope this helps!
 
You need to stop panicking and let the plants tell you what the need and how they are feeling, it’s not about you but about them. Try reading the cannabis encyclopedia by Jorge Cervantes but only as a guide line. The book has a lot of good information again you have to take it for what it is only to enhance your knowledge by trial and error.
 
Also post on the auto section their are a lot of growers out their with plenty years experience that will help you.
 
Doesn't look like a lot of soil in that ...cup? Rootbound? You may want to check on that. What's the medium and pot size for those? Age of plants? Sorry if you mentioned and I missed it.
Pots are 12l and buckets 10l, but I have some with just 6l soil, like 2 of them, the one that look good actualy :).
Day 22 or 23

Maybe keep the roots in mind if things go off. Especially when using worm castings. Those types of fertilizers are really good for strong root growth.
