Kann mir jemand helfen, es ist kurz nach Umstellung auf 12/12 passiert. Bei den Pflanzen handelt es sich um Stecklinge. Als dünger benutze ich biotabs.

That looks like heat stress. Did you have high temps for a while? Otherwise russet mites can cause similar looking damage, but don't think this is from them.

lower leaves are going taco too, light could be, but would not burn bottom so bad, especially when plant next to this looks ok. when i played with sugars and added too low ph, had same burn marks. recheck ph meter.

Hey, schaut so aus als würde ihr das intensive Licht / die Wärme nicht gefallen... Hast du kürzlich die intensität der Lampen erhöht?
