For some time now, I’ve been having problems with my coriander. The stems gradually keep turning purple, and the roots are not really developing properly. I’m not exactly sure what is causing it, whether they are too close to the light or whether it is an issue with the EC value or the pH value, and how the whole thing can be fixed.
Roots are forming, and there is no root rot, but there are not particularly many roots either. The EC value is constantly around 1.9, and the pH value is quite stable below 6, somewhere between 5 and 6.
Does anyone have an idea what the problem might be with the coriander stems that are slowly starting to rot or turn purple?
