Overdose of nutrient, maybe to much cal. Flush the nutrient out and use only ph correct water for the next days. The damage on the leaves will not go back.

Hi ! Dit lijkt me een schimmelprobleem. Je gaat gelukkig bijna oogsten. Probeer de luchtvochtigheid laag te houden, zorg dat de temperatuur op peil is en voorzie een goede luchtstroom rond de plant. Succes en een goede oogst!🤙🌱

Thought it was a calmag def, but now I don't really now.When I switched to flower, I started watching some rusty spots on the leaves of the gelato.

Chewed up leaves Wondering if I should be concerned? They have just entered flowering, I have noticed a few leaves bearing this issue. I use ties which have ripped some leaves due to me not being gentle, and I spray a mild cannacure solition regularly.
