Hi all, what's this? Disease, deficiency or damage? It is on all leaves except new growth. All theories are welcome. Attachment:

That's an interesting one. With the generally pale colour of the leaf and yellowing between the veins you definitely have a deficiency, whether or not that's causing the necrotic patches is another question... at first glance it looks more fungal or piercing insect. Can you post a few photo's of the underside of the leaf close up, as well as some of the entire plant? |

When I used to grow a lot of chard in the dirt garden, there was often a lot of this brown spot, which I thought at the time was due to insect attack of some sort, but I never did find out for sure. It happened on nice dark green leaves too, so I didn't think it was related to any deficiency. We still ate them, and there wasn't any noticeable effect on flavour. |

By any chance are you getting dew overnight, or water on the leaves from splashing or some other cause? |

I'm thinking it's probably either bacterial or fungal and is related to the water on the leaves giving it a place to start. I'd try to keep them from getting wet if possible. |
