Hello it seems you have calmag deficience. How do you try to correct it. You can use epsom salt which is the best for this. You can mix it in water and mist your plant for a quicker effect. Good luck. Bye

Leaves are gray/brown and curl down. HELP!
Im a first time grower and I cannot figure what’s wrong. I’ve been feeding it Calmag and Grow from Biobizz since last week. 1 ml/l grow, 0,8ml/l calmag. PH of water + nutes is 6.3. The soil is coco and pearlite. Did I give it too many nutrients? Did I overwatater?

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.

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 🙏🌱
