URGENT Help needed I burnt my plants with peroxide week3 flower

That looks like nutrient burn to me. 3% H2o2 isn't going to cook leaves like that. I have seen with HIDs (HPS, MH) plants get sprayed lights on and it cook them but LED unlikely.

WHy are you doing so much weird stuff? ozone and h2o2? Do you have powdery mildew or something?

The lights could have come on whilst plants were still wet from my second dosing of water.
Either that or it came out stronger than 3% ( I started with 500ml of 12% and added 1.5ltr of water so it was definitely 3%

Regardless of the catalyst to my burning the main question is , can they be saved?
I would have had 5 weeks left of flower as these are 3 weeks from switch so it would take atleast 7-9 weeks to pop some new beans to this same size of plant .will try get some pis up later but probably tomorrow morning

So you used half a litre of 12% h202 suloution to 1 1/2 ltrs of water , is that right. Were there instructions on the h2o2 sulotion ?

Definitely not nute burn because these turned from green to like this over 24-48hours
Basically I was using a sonic humidifier then I noticed a shit ton of black mold forming on my tent roof, and wallls mainly around the poles!

Panicked because I didn't want spores being released ontop my early flowers then coming to fuck me in late flower. Cleaned the tent with bleach and h202 + ozone to be on safe side.

What I do think I had prior to doing the above was mild light burn. Either way the plants are quite well recovered now just I can see yeild will be lower.

Exactly that. No instructions but that's just math. 50 50 on half ltr 12% = 1ltr 6% then 50/50 again= 2ltr at 3% .
Bare in mind I left this solution ( absolutely drenched)on the plant for over 12hours as it didn't dry completely before the lights came on.
I did notice damage to the leaf colour whilst still wet prior to lights on which I think was the h202 worsening existing mild light burn damage.
My lights are 800w strip bar light with Far red and UV diodes. Grow light Australia board.

looks like light burn, its not that bad though, i would carry on at this point, probably wont be as good as it could have been but i doubt it will effect things terribly badly.

If you have done that its way way way too much. The 12% is the percentage of active content in the bottle. That pecentage is only displayed in acrdance with the saftey laws for corosivs ect it isnt any thing to do with directions of use, just the percentage of the corosive chemical and the concentration of it in the bottle. It would be similar to fertilizer feed with eg 1-10-12 on the bottle wich is the concentration of those elements in the bottle. We cant use 100 % hydrogen peroxide as it would just corode what ever you aplyed it too. So diffrent concentrations are used for diffrent things. For the plant use they keep it around 3% - 15% and thats done for saftey incase it spils on the user it wont damage the user too bad til they can was it off. Your only suposed to use something like 5ml or 10ml of that liqid oxegen product per 10ltrs of your water soloution/ already mixed feed solution, that probably ends up being a very very low percentage of the actve ingident wich is safe for plants without causing damage.. That amount you used would of literaly fried your plants.
Everything that soloution you mixied is probably damaged beyong repair. Just concentrate on new grow if you want to keep the plants
