Burned upper leaf edges
Hi! Dark spots appeared on some upper leaves overnight. I don't think this is the cause, but I did a pretty heavy defoliation the day before. the spots only affects leaf margins and makes the tips curl up. The spots are brown, burned and slightly purplish. what could this be?

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 🙏🌱

Brownish Spots on 2 Older Leafs. Young plant.
I searched it up before posting this and what I found is: Leaf spot, canker, and fungus: Brown leaf spot, Yellow leaf spot, Cladosporium stem canker and Chaetomium fungus. Solutions I found in the comments below. What do you guys think? Can it be heat (a lot of hot days here)?

Bruising or nute problem?
I do not have enough characters here, please check diary for details. Some tops are showing some problems. The thing is, only a few and it does not seem related to light distance. My first thoughts is this is bruising, but I would like some more expert opinions.

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.
