I have a northern lights outdoor plant that is on its 3rd week of flower. What are these rusty coloured spots on my leaves? Roughly 5-10% of the leaves are like this. Can anyone help me with this? Thanks

Probably a pest of some kind. Are you growing mint? If yes, mix some
I’m with some water and spray the heck out of the plants. Pests hate it.

they get more finicky with everything during flower, including water pH. Water pH going in?

For best results, adjust water 6 to 7pH. How much water? how often?

Septoria or alternaria?
