Need some help, I'm really lost
Hi people, need some serious help here. The new leaves look like sh¡T. They are kinda yellowish and the tops are necrosed. Some spots on the leaves too! I added some silica in the last water but I don't know if was the cause. Soil pH varies between 6.5 and 7.0. Any ideas?

Rust spots on leaves, second grow and need some confirmation.
I'm noticing rust spots on my leaves, which I suspect could be due to nutrient burn or lockout, given the PPM is unusually high for this stage of growth. To tackle this, I'm planning a simple flush with some Cal-Mag, keeping the pH at 6.5. Does this sound like the right approach?

Discoloration and patches on the top sugar leaves
Leaves circled have gone lime green to yellow with the dark and light spots shown in the image. Is it light burn, wind burn or something more sinister?!

Add CalMag or Manganese? Still slightly discolored and veiny leaves on week 6
Calcium or Manganese deficiency? Last week had what I thought was early calcium deficiency. Gave it a dose of CalMag but now not sure if it’s still Calcium or possibly Manganese. I do mean manganese but I realize it could be a CalMag or Manganese deficiency as well.

From day 50 some leaves of the plant started to turn yellow. I had stopped nutrients due to an overfert problem. So, on day 50 I started with the nutrients again, but in lower doses. 2 week left to harvest. What should I do with this nitrogen deficiency? Should I worry?

Spots and discoloration on leaves.
The spots and discoloration are an issue. I'm in living soil and this is a Gelat.OG autoflower. Everything is dialed in near perfectly. Just the spots. Would this be the start of senescence? Any help would be greatly appreciated.

Preflower stage at week 3 ?!
Is it normal that my Bubble kush auto at week 3 is already starting preflowering stage ? if so is that why the first leaves are starting to fade to light green im not sure what to do at this stage. I stopped giving her biobizz nutrients and just plain water at 6 ph with 15 PPM.

Black spots on leaves
Black spots present on some fan leaves. During ~3rd month right now. Watering with HESI in Coco Coir, PH ~6 every time, 1/2 runoff water. For about 2 weeks prior to this, I also added very small amount of kelp powder. Soil seems fine.

I could be wrong, but it looks like my leaves are starting to show signs of deficiency or am I just being paranoid?

K deficiency?
in the last pictures you can see what to me look like an early deficiency of K. Since she is in the first stages of flowering I would say that's the case, reading the literature online i noticed a lot of similarities, what do you think?
