Hi everyone.
I'm very proud to say that after a month's holidays I came back to a flourishing garden!
However, a couple of the more mature leaves on 1 of my broccoli plants have a blackish tinge to them..Almost like windburn? Is this possible? It is next to some tomatos that aren't looking so hot and I'm worried about blight...
Does anyone have any insight?
Can I remove the leaves wthat have the discolouring?
Thanks so much!
I'd upload a photo but I dont have a camera at the moment!

Diseases of Broccoli
Is it like this

Black rot is caused by the bacterium Xanthomonas campestris pv. campestris. Yellow V-shaped lesions appear along the leaf margins with the V directed toward a vein. Infected areas of the leaf become dry as the disease progresses and the veins become darker, often extending into the stem.

thanks for the reply and for taking hte time to post the pic!
It doesn't look like that. It looks more....greyish?

My sister in law one left her peace lily outside and it became wind/sun burned and the leaves turned grey..that's exactly what this reminds me of.
I'll see if I can take a pic with my phone in the a.m.

Or the recent good weather!! Very Happy It sounds more like like sun scorch to me. One of my tomatoes is showing the same kind of silvery-grey patches after the BH weekend.

yes it looks like xanthamonas or black Spot to me a bacterial disease, could be seed borne or transmitted from overwintered brassicas, as far as i know there is no known complete cure.
