Hello! I've noticed some brown spots on some of my leaves, localized to one half of the plant. Any ideas what this could be?

I wanted to ask if you think this plant has mold or if it's just a major deficiency due to a blockage. I have an indoor plant next door with some plants growing with dark spots, it's in my previous question. Sorry for giving more information, I don't know what would help.

New grower with questions about burnt tips, browning/scrunching leaves and some pale/yellow spots!
I noticed Quick One had issues with burnt tips and discoloration by the end of week 1 and 2, what could've been the issue? Apple Fritter is looking sick, brown spots, what is that? Easy Bud and Quick on have slight yellow/paled spots on their leaves, only 1-2, is that normal?

First time DWC, day 70, 3 weeks in flower. Nasty rusty spots appear on lower leaves. Is this CalMag or else? Please help understand and fix, thank you :)
I'm using TA Tripart, current EC is 1.6 - ph 5.5-6.5. Everything was smooth until week 10. Two weeks ago I started adding Plagron Power Buds and Green Sensation. Yesterday added CalMag to see if it helps, but it doesnt seem to... She drinks a lot, ph mostly goes down, EC static

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?

Black tips and spots on the leaves
I'm having problems with the leaves. I estimate that the plant has about two or three weeks left to live, and I don't want to have issues now. Some tips are darkening, and spots are appearing on the leaves

Braune Flecken an den Blättern
Hallo zusammen, Ich habe seit ein paar Tagen diese braunen Flecken auf den alten Blättern meiner Pflänzchen. Die Wochen zuvor habe ich gedüngt, allerdings nur mit 1 ml BioGrow, 1 ml BioBloom & 2 ml CalMag von BioBizz — denke eher es ist ein Mangel. Vielen Dank für eure tips!

The leaves on the upper plant wake up today with a brownish spot. It’s not light burning for sure (ts 1000 dimmer 70% height 50-60cm). Feeding problems? The first two photos are dark brown, the last one is yellowish.

Brown Red Round Spots on 4-5 Fanleaves / fungus ?
Hey folks, I have this issue with one of my ladies. There are small reddish-brown spots on 4-5 fan leaves, while the other plants don’t have anything. What could this be? I think it’s a fungus, but I want to be sure and know exactly what it is before I start treating it.

Tache cuivrés sur feuille.
Je me demande si les tâches cuivrées sur les feuilles de ma plante de cannabis et d'autres plantes sont dues à une carence en calcium ou en phosphore/potassium. Les feuilles affectées sont généralement les grandes feuilles, souvent nourricières. Voir agenda. Je vous remercie 🙏🌱

Day 4, after emerging. Is this coloration on the cotyledons okay?
Humidity is 55 - 70, temp is around 20-24c, 50w full spec led It's my first time, and i think i have been watering it too much I also fed it 2-0-0 npk water with 4ml per liter and I since learned it's not okay. Will it recover? Is this too little grow for day 4?
