Problem with plants in the 3rd week of vegetation.I'm posting again because I accidentally marked it as resolved.
I was using BioBizz CalMag from the beginning, but when I switched to Advanced Nutrients, I stopped because Ph Perfect Sensi Coco Grow A and B already contain CalMag.

Still cant figure out what's going on with this plant. EC was over 2 for a couple of days but has since been taken care of, last reading was .83.Is this a deficiency or some other kind of issue?
Some have suggested a p or k deficiency, but I feed Jack's 20-10-20 peat-lite so I would be very surprised if it was a P problem, and the problem seems to be all over the leaves, but a lot of them start from the base of the leaf.

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?

Organic peat controlI 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?
