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....

Foglie bruciate.Ciao ragazzi?spero vada tutto bene. Ho delle bruciature nelle foglie di una sola pianta, ho dato bio grow e top max biobizz. Umidità 50 % temperatura 27/30 °c purtroppo. Io penso sia dovuto alle luci troppo vicine, ma volevo un vostro parere. Grazie mille.

Saw this first day of 12/12 Pretty sure this is just where I got nutrient solution on my plant yesterday when watering unless it's something else? I pulled these leaves off 1 plant when lights came on this morning. Every Plant looks 💯 great besides these 3 leaves, all from 1 plant rest of plant is great.

Cotyledon issue from seedling Have seedlings from Auto Colorado Cookies (Dutch Passion). One already has cotyledons, but not opened yet. I see some yellow and bigger brown spot of the tip. In the beginning I had 250 PPFD, could this be the issue? Now I am around 100 PPFD and put the light a bit up. See photo.
