Could this be "early blight" ?.
" causes brown patches with concentric circles ........ worst in warm wet weather "

Found this nice illustrated pdf download on tomato problems Here.
Also suitable for brassicas.


Also found this online tomato disorder identifier Here

Excellent, thank you very much! Interesting stuff that.. I've saved them all to favourites. !!

Hi, I am new so I hope you can help. I just found some pale beige to translucent edges on my tomato seedlings (in a greenhouse.) this seems to be spreading fast is it a disease or nutrient deficiency?


I have tried accessing the resources given by richyrich7 but they are not available to me ...perhaps not to someone in Canada?

my greenhouse is heated (via access from a wood heated house.
I have tried to upload a photo but don't see it yet

Welcome to the site robin 

Couple of questions - is your greenhouse heated all the time?

And if you look a couple of posts further up there's two links given by richyrich7 - have you looked at those to see whether you can identify your problem from them?

A piccie would help, see here for how to load one to the site

Hi Robin & welcome to the forums.
The tom's are in a greenhouse are they in a heated propagator ? is the green house heated?
Sorry loads of questions lol

Like Yorkie suggests have a look at the links or possibly post a pic.

thanks for any help

Looks a bit like scorch to me.  Are you watering them and leaving them in sunlight?  Are they touching an edge of a greenhouse or window?

I have taken off all the leaves with marks on them and am being more careful not to get water on the leaves. I don't see any more spots coming. thanks for your help! Isn't it amazing to get information on line from across the world?
