Looks like its getting a bit to cold for her. Temps below 16C/60F will cause stunting and hinder nutrition uptake.

Organic peat control
I think my plant is being eaten but gnats and it looks like nutrient damage on it but I haven’t given ANY nutrients to it. What should I do? Can you diagnose my plant? Any remedies? I heard cayenne pepper can be used for a pesticide is there other things? Does Neem oil work well?

Dark tips
it seems to me that the tips of the leaves have a very dark color, it looks like an excess of nitrogen but in three weeks I have never fertilized and the only additions to my biobizz light mix are a sprinkling of guano kalong and 10% of worm humus biobizz.

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?
