Personally I think it's the hydrogen peroxide 12% mix, the hydrogen gave one of its atoms to the neuron of the Diatomaceous earth metal clay. With help from heat

What’s happening with my leaves?It’s my first grow, I don’t really have a clue what I’m doing… read online, only have a 100 watt led lamp, 24 Celcius and 40% humidity. I used a testpack from biobizz and sofar my gorilla zkittles auto is looking ok!
But since I’m in flower week 6, I have curling leaves, normal?

I don't think this is nute burn...So I thought I had a case of mild nute burn but I haven't given the plants any Bloom or Calmag since last Friday, only water so I'm wondering if this is a nute burn issue now. Could it be my PH? Last I tested my run off it was at about 6.65. What's causing this?

Getting out of the ideas - VPD, nutrients or deficiency?I'm getting out of the ideas as the foliar symptoms proceed.
Lowered EC down to 1.8 from 2.2, pH in range.
VPD is getting problematic as the plants seem to be respirating a lot during the day and it rises tent RH sometimes up to 70% - exhaust duct fan wont keep up. Temps 22-24C

Twisted, yellow/brown tips.Hi,
My plant has shown signs of a nutrient excess throughout its complete cycle. It keeps to the tips of younger the leaves that have a tiny twist in the end. I don't think it's the light as it also affects leaves in the lower canopy. I keep on flushing but nothing changes.

Surplus or deficiency?Can't tell if there's a surplus of nutrients or a shortage of potassium? One plant looks like nitrogen burn and the other two look like theyre maybe a little k deficient. Was thinking of chilling out on the feed on the burnt one and just feeding micro to the other two. Thoughts?

What are my leaves telling me?Is this light burn? Nutrient deficiency/excess? It is only happening on the top leaves, the lower leaves are just fine. The light is rather close to the plant, but she is outgrowing my tent. Thanks in advance for the help! I really appreciate it. 😀

Nute light burnOkay I think I learned a lesson, 1/4 nutes next time (or nothing at all) seeing I'm seriously nute burning my plants, also one of the girls is about 20 cm from my light... Anything I can do to maybe calm down the situation? Flush? Never tried to and wasn't planning on doing it...

What to do with crispy curly fan leaves that do have some resin on them?, I'm already on flushing.Some fan leaves are starting to look a bit too crispy and curly, they do have some trichomes, I'm 3-4 days into flushing.
I'm not sure if the dry matter can "contaminate" the buds somehow, and don't know if I should do something about it, I'm planning to get some "bubble hash"

ProblemeI have burnt leaf tips and various other questions regarding the leaves. I would be very grateful for help. Picture 1-7 calmag deficiency? 8-10 various problems, what do you think about that? I'm interested in your opinion on the last 2 pictures. It's my first time, I have no comparison. 6th week of flowering.
