Amico mio guarda.le macchie di ruggine sono dei funghi.. ti consiglierei di abbassare l'umidità perché quella aiuta la proliferazione... E più vento nel box penso che dopo è apposto.....poi sé hai già tagliato via le foglie tagliate,meglio....

Browning leaves sections of leaf surface discoloured Day 18 leaf worries, browning areas, slightly metallic shine. I think from reading it might possibly be a phosphorus deficiency but I’m not certain so though I’d ask for advice. Thank you for your time and all answers are appreciated. Have a great day!
