Looks like acid burn. Maybe a drop of nutrients hit the leaf?

I think my plants are suffering a Phosphorus deficiency due to lockout due to low ph of soil. My first flush only helped for a while. As soon as the medium gets too dry damage resumes. I went to check on them yesterday and the amount of damage they took in 24 hours was pretty bad

Yellow/Brown/Spotted/Crispy Lower Leaves
What is wrong here? Gave an extra dose of nutes but the problem only seems to be getting worse and spreading up the plant. Definitely effecting the bottom leaves more. Others said to just increase N-P-K ration, but this seems like something specific.

dark, curled downwards and brown fan leaves
Why are the fan leaves dark, curled downwards and showing brown marks originating from the edges? Had an issue of dark and curled leaves for a week or 2, did think it was getting better (N2 deficiency) but now suddenly after not watering for a day the leaves are going brown.

Ph issues part 2
Hi guys! It has been a while after flushing, repotting into bigger pot with fresh medium and feeding her only with water. I bought Sensi cal mag extra and I need your advise if it can be used together with BioBizz nutrients, I could get only this brand in my local store

Leaves keep turning brown and yellow
It all begann with what I thought was light burn. I then considered it CalMag deficiency. Giving it CalMag did not stop it. My current guess is too low pH due to strip inaccuracies, so I gave it around 8 today instead. What do you recon, why could it keep getting worse?

End of Cycle or something to be afraid
Hi everyone, I think the brown leaves just reflect the end of cycle (WG started flushing 4 days ago, DSD33 today). I don't see signs of mold or something rotting, brown leaves do not detach, both plants show already some amber trichomes. What do you think?
