Was ist das?Meine Gorilla Skittlez (siehe Tagebuch) wird relativ hell und bekommt komische Flecken.
Ich gieße abwechselnd mit Hesi Bloom (2,5ml/L) , 1ml/L Calmag und nur Calmag 1ml/L
Dachte die Flecken kommen von zu wenig Calcium Magnesium.
Jetzt steigt aber mein PH Wert von 6,8 auf 7,4.Leaves. Color - Dark-brown

I wanted to ask if you think this plant has mold or if it's just a major deficiency due to a blockage. I have an indoor plant next door with some plants growing with dark spots, it's in my previous question. Sorry for giving more information, I don't know what would help.Leaves. Color - Dark-brown
