Schwarze Spitzen und Flecken nach Neemöl-/Kaliseifenbehandlung in der Dunkelphase. Schimmel? Dran lassen oder abschneiden? Bitte um Hilfe!
03. November: Zu Beginn der Dunkelphase, einen Mix aus 200ml Wasser mit 2ml Neemöl, ein Schuss Rapsöl und 4ml Kaliseife, auf die Pflanze aufgetragen. Grund dafür ist ein Befall mit weißer Fliege. Alles habe ich nicht aufgetragen. Heute sehe ich schwarze Flecken. Ist das Schimmel?
