What nutrient burn is this?

Looks okay I would just water with water ph’ed so that it brings you medium into the center of the ideal range ( whatever that is for soil), with a bit of runoff to get out some of the undesirables and help get closer to ideal ph throughout your medium

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.

It’s been a couple weeks and you were totally right. I now have a host of soil problems along with insect problems in my tent. I’m honestly considering scrapping the whole grow and starting over.

Seriously, it seems wrong as fuck, to pour hydroden peroxide solution on to your roots, buuut, hydrogen peroxide is dangerous to us as humans and practically harmless to plants. I have witnessed a tomato plant suffering from root issues resurrected by a jug of hydrogen peroxide solution.

The role of hydrogen peroxide in regulation of plant metabolism and cellular signalling in response to environmental stresses - PubMed

Hydrogen peroxide (H2O2) is produced predominantly in plant cells during photosynthesis and photorespiration, and to a lesser extent, in respiration processes. It is the most stable of the so-called reactive oxygen species (ROS), and therefore plays a crucial role as a signalling molecule in...

I just post this to show that it isnt some foreign chemical to plants, and applying it to the outside of a plant has little to no negative effect.

Had to do this a couple times over the past 10 years. Always hurts to do it but you're actually destroying a lot of bad organic matter and putting oxygen into your root system, my plants always did fine afterwards. A lot of people used to run hydrogen peroxide in their cloners and even hydro systems before we knew that bacteria and fungi on roots were a good thing if the environment is kept aerobic.

What was the ratio of browns to greens in your compost? What did you use as browns? also I would suggest never going above 1/3 compost in your mix unless you're getting extremely high quality light and airy compost usually it'll look more like a semi-dark chocolate than a black and will have a different feel that's kind of hard to explain. Usually compost is easily compacted if the ratio to your aeration is off. A general rule of thumb is 1/3 compost 1/3 aeration 1/3 peat/Coco/pitmoss/etc.


Also if you do use hydrogen peroxide growing organically you're going to need to innoculate with something afterwards, it will kill all of your soil biology good and bad. I usually don't brew teas anymore but I'll just stir about a cup of good ewc/vermicompost and some humic/fulvic acid and water it in. Using something like em-1 or bokashi would also probably be a good idea to have some facultative anaerobes in your soil to try to outcompete the really bad stuff to at least some extent.
