Flecken auf Blatt und Halm oder Helikopter-Mutter
Die 2 Flecken auf dem vorderen Blatt und die dunklen Stellen am Halm beschäftigen mich ein bisschen. Glaubt ihr, die Pflanze hat ein Problem oder mache ich mir mal wieder zu viele Sorgen? VP 10. Steht im 11l BB AllMix und wurde einmal am Anfang der VP mit 3l gewässert.

Cal mag or nutrient Burn
I have 3 Automatics. I made the mistake of planting the into BioBizz Allmix, which is pretty strong for Autos. Strawberry Gorilla and Aplle Strudel seem to be fine. My Orange sherbet not so much. Is this Cal/ Mag defficiency or nutrient burn?

Deficiency?? Excess? Neither?
Grown this strain before and had the same issue.. not sure if its a CalMag deficiency entirely. pH has remained at 6.0-6.5 or so in soil and didnt show signs until recently, seemed to have worsened after just two days of only CalMag and Ro water so I bumped up the bloom nutes.

Are those nutrient defficiencies? Which ones?
A plant had interveinal chlorosis on new leaves and then proceeded to show brown patches between veins on middle leaves. Another has coppery brown spots on leaf edges on the middle of the plant. Both were rootbound in living soil (peat/perlite/hummus + ammendments).

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 🙏🌱
