Oh Bro, considering the good general health of the leaves, these spots are very suggestive of droplet sunburn.

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

Verfärbte Blätter
Verfärbte und teilweise vertrocknete Blätter bei meiner Autoflower in Woche 9. Nährstoffmangel, Nährstoffüberschuss, zu viel Licht? Grobe mit biobizz biogrow, biobloom und topmax. Woran könnte es liegen?

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?

What's wrong with the leaf?
There is a problem with the leaves. I saw this problem in all the same seeds. However, I did not see it in the different types of seeds that I grew in the same place. Please help, what is the problem?

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!

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

N or P deficiency?
Need help to understand if this is P or N deficiency. It's on the lowest fan leaves, one is more pronounced than the other, and it's mostly on one side. Stems and veins look like they're giving hints of P def but from what I searched leaves look like it could be N def.

Pest infestation left my plant folded and weak. I treated it, but now blacked out leaves?
Ants were farming an oval shaped bug's secretions that was eating my stem and going underground, leaving a trail of a film-like substance. Treated it with neem oil, cigarette butt tea, garlic and dishwasher soap to fend them off. Black leaves now. Tips?

Two problems in a week. I diagnosed the first one based on similar grow questions (: maybe not right )
First three photos appeared a week ago, I decided that it is calcium and took a more reliable Ph meter, maybe not right, but no new spots appeared. Second problem at the end of the week, 3 days after defoliation 2 large lower leaves and 2 leaves inside. 30 hours after watering.
