Any ideas what this might be on my tomato plant?

Can anyone tell me what this is on my tomato plants (its the last two pics not the first two) from last year?

I cant get the link to work with the URLs so you may have to copy and paste it in the address bar.

I couldnt diagnose it last year and Ive spotted it on one of my plants (just one leaf mind - swiftly removed). I lost all my tom plants in the end as I didnt know how to combat it.

So this year ive been really, really careful. Only two plants per grow bag and even added extra compost by inserting a deep ring around the hole, regular watering with tap water and made sure no water has got onto the leaves.

Im determined to have a crop of toms this year.

Thanks

not really - I would guess that the last two pictures are water droplet damage.. so it might be the case tht this progresses to the brown spots. (or it could be blight starting...)

where are your toms? outside?

nope dunno what it is.. maybe someone else can diagnose. if they were mine i would pick off leave with brown bits and dispose carefully...

It looks like water damage to me, did they get the early morning sun when they still had dew on their leaves ?
Healthy tomatoes exude water droplets on their leaves at night and outdoor ones also get dew, both of which act like tiny magnifying glasses that burn the leaf.
If it is that, then it's nothing to worry about as long as there's plenty of other leaf area to compensate.

It's certainly NOT blight, that's a totally different look.

If it's any consolation - my indoor plants have the same thing but only on the lower leaves that aren't shaded first thing in the morning.

I agree with Odsox - nothing to worry about.

It's scorch caused by water droplets on the leaves for too long in bright sunlight (it act's like a magnifying glass). It can also be caused by water droplets being on the leaves for too long in general, or even by a strong plant food solution staying on the leaves. It isn't contageous, and won't cause any serious harm, but try and water early in the morning, and if you do have to water in bright sunlight, don't get any on the leaves. You don't need to pick the leaves off, as that will just reduce the plant's ability to photosynthesise.
