Looks like acid burn. Maybe a drop of nutrients hit the leaf?

Orange Spot in first set of leaves
If you can see Veg Week 1 Photos, Photo named Day 7 Zoomed, I have been seeing these dots for 2-3 days now. What is it? how can it be solved? FYI - These were the first set of leaves, others look healthy. My guess - nut water got sprinkled or cal/mag deficiency.

Tache cuivrés sur feuille.
Je me demande si les tâches cuivrées sur les feuilles de ma plante de cannabis et d'autres plantes sont dues à une carence en calcium ou en phosphore/potassium. Les feuilles affectées sont généralement les grandes feuilles, souvent nourricières. Voir agenda. Je vous remercie 🙏🌱

Why is my WW seedling browning?
I have a White Widow seedling that is showing brown spots. I am not sure if the LED light was too close, or if it is showing nutrient deficiencies/excesses. pH=5.8, PPM=160 (80ppm in well water).

brown spots on older leaves
The brown spots are appearing more prominently on the older leaves. Overall, the color of the leaves is rather light green compared to other grow diaries. What could I do to fix the deficiency?

Brown dying leaves
What is going on with my leaves? Even the sugar leaves are starting to die. Sprayed with optic foliar switch to prevent male flowers popping up a few weeks ago so could be that.

What's causing my brown crispy leaves!?
Over the past week my plants have taken a turn for the worse. Many leaves went from yellowing to browning to completely crispy! Other leaves have brown spots on them and some of the stems are purple.

Brown spots
What is this? It's affecting newer growth, first or second set of fan leaves off thee top of the colas. Also, this drooping, is this stress from the light? This is the center of my tent, and would appear to only affect tallest colas of this plant.

Deficiency?? Excess? Neither?
Grown this strain before and had the same issue.. not sure if its a CalMag deficiency entirely. pH has remained at 6.0-6.5 or so in soil and didnt show signs until recently, seemed to have worsened after just two days of only CalMag and Ro water so I bumped up the bloom nutes.

Could someone help me to identify the issue my plant has?
This girl isn't looking healthy anymore and I need to figure out why. What I did: I topped her pretty early but she recovered well (you can see it in my grow diary). A week later I transplanted her from 0.5L pot to her final autopot 14L. After that she had a hard time recovering.
