1. Over Fed (seaweed?)
2. Burnt? Cauliflower..
3. Calcium Deficiency
4. Hydrogen peroxide 12% Food-grade 30/70 Mix.
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

Cal-Mag and N Deficiency in Flower? Thanks!I'm guessing the yellowing and brown spots (in Wk 8 pics) are related to Cal/Mag and maybe a lack of N? Would love some advice from someone who's seen this before
Thanks! I'm seeing this in all my grows to some degree- using FF trio and FFOF but not for much longer

Possibly Potassium Deficient? Based on ALL the pics I could find, but not sure.I noticed these brown splotches and leaf edges on one area bud and pistils of my Orange Sherbet last night. Based on what I can find online, this might be potassium deficiency?
This is mostly on one spot near darkest edge when tent closed. Thanks!

Brown spots, serrated edges curling up - calcium deficiency?This is a Barney's Critical Kush auto that's at about day 57. She's into flowering, but I've just started to notice some brown spots on leaves with some slight tip browning, and the serrated edges on the leaf are curling up.
Is this just a straight calcium deficiency?

Is this pH related?Hello, mates!
Anyone knows what this could be? Searching I found that it could be pH related. I use pH controller from ferts (pH perfect from advanced nutrients) since the beginning, so I think it's odd that it could be a pH issue.
p.s. 3.5 weeks of flowering
Thanks 🙏 🙏
