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

Please say it ain't bud mold :(
Noticed a brown spot on my center cola last night. This morning it progressed so I removed it. I'm noticing browning on nearby leaves. It may be nute burn (I have been heavy on them), and I did recently increase light intensity to full two days ago, but my temps are ~74f. Pls no!

What is causing this Leaf discolouration overnight after a lot of tent work yesterday
Spent a lot of time in the tent yesterday. Everything was fine and this morning there’s bad discolouration on the leaves of some plants. I did lower the plant (was way too high) so may beight burn - but it’s only on some plants I did make two mixes of water/nutes

Copper spots
I noticed these copper spots and leaf tips about a week ago, it doesn’t seem to be progressing too fast. The plants otherwise seem to be healthy but what is the issue? Magnesium Def?

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 🙏🌱
