What nutrient burn is this?

I threw some of my composted soil (not sure exactly what was in there but mainly fruits, vegetables, egg shells and bread) into my pots for this grow just to see how it would go. Now I’m starting to see some twisting leaves and browning/drying. Not sure what nutrient is causing this and how to fix it besides flushing which might just break down more of the organic matter that’s causing it.
Curious what people might think. I’m open to any feedback.

just to get ahead of any comments I will be moving 3 of these plants into another tent. 6 would be way to crowded for what I’m going for.

That's Barney Burn.

3 of the plants are Barney’s Farm Purple Punch. But not the ones with the burn. Is Barney’s know to burn easily?

Lol. I got you man. I was joking about the blurple lighting.

But seriously, it's gotta have something to do with the compost. Is this an outside bin, and did you compost it long enough? I think pH when I see curling leaves usually, but those brown spots look kinda like a fungal thing. I don't know for sure.

If you suspect your soil has undesirables you could try hydrogen peroxide, then maybe try add back some good stuff with a probiotic,

It's the bad kind.

Nitrogen excess judging by the leaf claw. Some strains are just picky assholes and require some tweaking the feed.

How green were you composting? The inputs into your compost were probably really high in N like dark leafy greens.

How much did you put in ratio wise?

I think you’re right. I probably didn’t compost long enough and it’s too high in N. I had it outside in a bin for over a month mixed with some old potting soil from and old grow.

I put about half and half with other half being Kellogg’s potting soil (not my go to soil btw)

whats your ratio for hydrogen peroxide? What would you recommend for a probiotic.. a tea or recharge?

Hahaha aight got you.
It could literally be all those things lol! I don’t test my ph regularly and I don’t think I composted long enough.

Yea thats a bit much,20% max I go about 10%.Not enough air now.Needs perlite. Compost just goes to mud when wet.

I have used this as a probiotic. Look up the benefits of the various bacteria, pretty interesting, and interesting where the different bacteria live.

One thing with compost is that it can be acidic especially when using food scraps if it's not aged long enough. I don't know if that has anything to do with your issue but something to think about in the future.

The leaves are

I forgot to mention that I mixed the used soil from my previous grow into my compost regularly so it’s probly 70% pure compost and 30%used potting soil.

Let me say some things, none of which I can prove but I believe they make good sense.

Compost can be dangerous, my compost in my place is a worm bin. But it is full of probably thousands if not more kinds of bacteria, protists, fungi, viruses, etc.

This is why padawan warrior asked if it was composted long enough. When a compost is too fresh, you can have larger populations of species of microbiota that are not desirable next to a fresh plant. FOR INSTANCE, when you have a pack of strawberries on your counter, and they start moulding, that can actually be botrytis. https://www.google.com/search?client=firefox-b-d&q=botrytis+strawberry

Botrytis is the villain behind Bud rot. I guarantee you there is Botrytis in my compost at times, but when you compost long enough other populations of microbiota take over and dominate. Properly composted material should smell pretty close to soil. My worms fuck shit up and I go from rotting material to soil fairly quick, compared to just compost.

I would not freak out and dose your plants roots with hydrogen peroxide, but if things keep getting worse before they get better, you might want to consider if your plants roots may be fighting a losing battle in that high compost-soil mix.

These are thoughts, do with them what you will.
