Heavy burn, usually either too strong mix or insanely low pH. Your grow heavily compromised, unless its coco, then flush flush flush with correct ph ASAP !

Can anyone tell what is causing these yellow tips on new growth on this plant?
I noticed my DLI was around 42 at the top of this plant so the light may have been too strong, or it could be a nutrient issue? Using CoM Stonington soil, plant is 26 days old. Haven't added any nutrients to the soil yet.

Yellow tips
Dont know why but one of the girls is suffering from stress. I think this is the cause for the yellow tips or do you have a other opinion? I did LTS training every two to three days, maybe therefore? A other reason could be light burn. But with a distance of 50cm I dont think so

Seedlings with yellowing leaf edges
Any insight on what may be causing the yellow edges on these seedlings? I'm reusing FF Ocean Forest that I used on my last grow. I didn't amend the soil in these containers as I didn't expect they'd need anything before it was time to transplant. pH was good at last harvest.

Hello! These spots appeared on a leaf of a GG#4 from Zamnesia in its fifth week of vegetative growth. It's not something I'm worried about, as the plant looks healthy and is growing vigorously. But I've never seen this type of spot before and I'd like to know the possible reasons for it.

Why is one leaf yellow AND shiny?
Plant has one leaf that is yellow on one side, and shiny/dark and curling up on the other side? From what I've read those are 2 opposing issues (light burn or nitrogen deficiency/or toxicity) the others are pretty much uniform, Could this be from getting water droplets on leaves?

Halb gelb, halb grün
My plant is currently showing slight potassium deficiency. But somehow only on one half of the plant. The other half looks well-fed. Can someone explain this to me? Like, why doesn't the deficiency affect the entire plant?

Please help identify my Problem: Yellowing leaves with veins showing and some necrosis spots in third week of flower
The odd thing is that only some leaves in the middle of the plant are affected. My thoughts were Nitrogen or Manganese deficiency or maybe light burn (why in the mid of the plant tho?)? I feed Biobizz Bloom, Grow and TopMax, no Problems until now.

Yellowing in the top?
What's with the yellowing in the top? Is it normal? It's in a very nice soil mixture and I've fertilized it with Osmocote, a popular slow release fertilizer: https://icl-sf.com/mx-es/products/ornamental_horticulture/osmocote-plus-standard-5-6-a903226-15-9-12/
