Black leaves, need help

[Firro]

Hi,

i have a problem with my SCH and Chaze . Booth are 80 Days Old (They are Automatics, Breeder says 105-120 days from seed to finish) and stay on my Balkony in Germany.
Since one week they become black leaf tips and now black leaves. They are in 11 Litres Soil (BioBizz Allmix).

Here some Photos.

Thx

Looks like the start of P-phosphorus def... seems odd that some of bud leaf is suffering as well !

Are you feeding any nutrients ?

Or maybe spider mites - that would help to explain why it is so spotty...
