Auto seedling discolouration
This discolouration has appeared on the leaves of one of my two gorilla glue autos, it has been there since the first true leaves which makes me think it could be genetic? I’d like to know if anyone has more information on the cause or if anything needs to be done about it.

I found small spots (similar to rust spots) on the 2 ladies now. I saw something on the lower leaves. Can someone give me advice on what this could be or how I can get it under control so it doesn't spread further? Thanks in advance!

No_Clout
Their appears to be little brow spots/specs scattered on the fan leaves, I feel like I’ve seen it before but completely forgot what it was so if anyone knows if it’s a deficiency of any kind it would be appreciated. I ruled out nute burn because only one out of four has it.

I'll just leave this here.
Only a few leaves, but should I be worried? Last few waters have only had calmag to see if that helps.

Calcium or Phosphorus Deficiency?
One of my 3 Cream & Cheese has upper leaves on 3 stems/colas per the pic. The lower leaves are OK, the other 2 plants are fine. Thought calcium at first as phosphorus is more lower leaves? Maybe just add CalMag? Thank you so much!!

Nutrient Deficiency
Is this a PH issue showing or nutrient deficiencies (possibly caused by bad PH anyway, at 6.2 atm higher from earlier in week.)? Possibly magnesium deficiency, looking at pics. Anyone confident? Been hot in tents as well but water temps kept decent about 68-70.

Hey guys, i noticed today that very small brighter spots have appeared on the bigger leaves. Is this something i should be worried about? Is it because of the 20hrs light schedule? Should i switch to 18hrs? Thanks 😨

Leaves dying
I removed these dying leaves, they were burned, with signs of necrosis and curling down. Now the plant siting next to the "sick" one started to show some early signs, similar to what her sister showed weeks ago 😪 Does anybody know what is going on?

Need advice as soon as possible. Please see last few pictures of DoSiDos week 3. Am I looking at mottling here? Soil ph maladjusted? Please help if you've seen this before, and what steps do it take moving forward (or am I paranoid, IDK). Thank you!

Please look at the leaves shown, orange and dried parts. I asked a similar question earlier but these look more damaged and I'm wondering if it's worsened due to my setup. Wind damage from fans? Water damage from humidifier? Light or heat damage? Managing VPD is tough. Thanks!

Some kind of deficiency?
World of Seeds Strawberry Blue. Pretty slow, uneventful life this far (on me). What seems to be wrong? Veg and a lot of light. FoxFarm soil. Half to full strength of the General Organics line.
