Brown spot
Experimentgreenanswered grow question 4 years ago
I think if you're only having just that one spot, and 1 tip, it may just be a small problem that's corrected itself. Calcium can cause those brownish spots but it would spread, not just once leaf.
I'd say just keep the ph fixed like you did and watch for anymore spots.👍

Have you checked underneath the leaf for bugs? Or can just be a drop of nutrients burnt by the light?

Natural or Problem?Is this natural yellowing or is there a problem? pH to 6.3 and runoff is 5.7. The stem is awfully purple, watering/feeding is where I struggle. 1st pic - 4/21 and 2nd pic - today(4/24). Seems to have escalated over the last few days. Do-si-do auto about 10 weeks.

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.

Brown Red Round Spots on 4-5 Fanleaves / fungus ?Hey folks, I have this issue with one of my ladies. There are small reddish-brown spots on 4-5 fan leaves, while the other plants don’t have anything. What could this be?
I think it’s a fungus, but I want to be sure and know exactly what it is before I start treating it.
