Schwarze Spitzen und Flecken nach Neemöl-/Kaliseifenbehandlung in der Dunkelphase. Schimmel? Dran lassen oder abschneiden? Bitte um Hilfe!
November 3: At the beginning of the dark phase, I applied a mix of 200ml water with 2ml neem oil, a splash of rapeseed oil, and 4ml potassium soap to the plant. The reason for this is an infestation of whiteflies. I didn't apply everything. Today I see black spots. Is that mold?

Leaves burn
Hi! Is this nutes burn? Damage is on the upper/middle part of the canopy on very few leaves, but many more have black tips. I’m puzzled because during veg I was feeding the plant higher ppm than now and never had a problem!

Hey friends, can you tell me what this could be? Should I be worried? It seems to be doing fine and it's the only leaf with spots, could it be due to some water accidentally falling on it? Thanks
