Hi everyone.
Can anyone one shed some light on what these brown/yellow marks are and a way to get rid of them?
I’ve read that they could be nutrient burn or the incorrect ph of the soil. But ph is between 6 and 6,5. Measured with a ph probe. And I’m giving them the minimum dose of 2ml per liter of nutrients. Giving nutrients one watering and the ph balanced the next. So alternating between the two.
TIA.
