My northern lights auto started preflowering a couple days ago, and then I noticed this morning the new growth on the main top is coming in a bit twisted/weird. It might be a little to early to tell but i suspect either too high of a pH or a possible light leak but i’m not sure!

One of plants looks disformed. Should I chop it or risk it becoming hermie and time waste? You can compare these two in my grow diary. Discard it? Keep it?
One of my two plants (same strain, same seed batch) is significantly weaker than the second. It is disformed from day 1, looks ugly. Is it just a stunted grow or bad genetics? Should I chop it? Can it become hermie and spoil my harvest and waste my time? Drinks less than 2nd.

Heat stress? Light stress? Nute burn?
Hi y’all Since my girl started to flower the top leaves near bud sites have this weird cupping downwards look. I doubt it might be a nute burn since I already gave her a good flush. I think the heat might be the main issue (86-87degrees during day). What do u think? Day38autoflwr

What causes these colour smears
Jack Herer outdoors. None of my grows have presented a colour smear on the leaves, as this example shows. Left & Right of my hand shows 2 leaves with a colour smear on them. Any ideas or recommendations? Thanks Gang !!

Been discovering these little burns and holes on all the plants, Pic 2, 3 and 4. I'm assuming the burns are the precursor to the holes but I'm unsure, maybe they're not related. Any clues as to what this is. I want to stop it ASAP Rocky

What's going on with my clones? Do not have much information to add. VPD is not terribly off, DLI around 25.
What's going on with these clones? Not sure what it could be. They could possibly be rootbound. They should have been transplanted a few weeks ago but I did not have the space.

The young seedling leaves seem to have some sort of bruising. The young fan leaves are fine though, is this something to be concerned about or is it quite normal?

Calmag or Potassium deficiency
Starting to show hard yellowing on plant #2 looks like it can be calmag Deficiency or Potassium Deficiency. I gave them a bit extra calmag a few days ago and it seams like things are not improving too much.

Do I have too many leaves? Should I have been more ruthless in the early weeks of the flowering stage? I also have variegation on one of the plants, is this a disease or deficiency? The plant seems healthy enough though

Dark dots in leaves. Lamp burns?
I saw this dark dots in leaves but only she has it. She was exactly under spider-farmer sf1000 at 30 cm. Now I moved to other softer light at 40 cm. What do you think? Lamp burns? They're dry and curl up. Some images are edited for better appreciation but you have also originals.

Rusty Spots
I've got some rusty splotches on leaves, I am thinking possibly a Cal-Mag deficiency. Any help appreciated. Will be addressing the issue tomorrow. Not from watering as I water direct on soil.
