Oh Bro, considering the good general health of the leaves, these spots are very suggestive of droplet sunburn.

Could be dry areas in your root system if your using fabric planters.

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.

I flushed it because some leaves were showing some Nitrogen Toxicity. Run off was coming at 3000ppm and I fixed it to 1500. Now the older fan leaves are yellowing with some brown spots (check the last picture). It's a deficiency? Should I increase nutes? Thank you very much!

Is this Calcium Defic? What to do to fix?
Week 9 flower. Rust spots on leaves. Starts at top. This can only be calcium defic from ALL the research I've been doing. Can anyone chime in? I foiler spray a CalMag before lights out and I've added some more to the nute mix. 6.2 pH, runoff seems good.

Nutrient deficiency? If yes, what's the best course of action to salvage the situation?
First time grower of 3 autos, at week 8, lower leaves started turning yellow, top leaves started to get smaller/develop brown spots 2 weeks ago. Is this a nutrient deficiency problem? Soil should have been fertilized for 3 months, but I'm thinking they burned through it.

Too soon for leaves to be turning brown and curling!
The auto widow circular leaves are curling at the tips and the tips are turning brown, and one of the pineapple kush auto circular leaves is not only brown at the tip but looks like about a third of it on the end is gone. See photos. What might be going on and what can I do?

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 🙏🌱

Would putting off my first feeding for a day or two do this much damage to the plant? I've given it 2 feedings since then and hoping it's on the right track as the new growth is nice and green.
