Tomato spots!! Does anyone know what this is please?

[colliebird]

Hello,

I have 10 tomato plants growing in my greenhouse and one of the plants has spots on it’s leaves which I can’t find the cause of. I’ve Googled lots of sites with photos of tomato leaf problems, but they don’t resemble mine. Would you be able to tell me
what is the problem please. They are watered well and keptmoist. The greenhouse is shaded by whitening the panes, otherwise it is far too hot. On very warm days the door is left open. There are also two automatic opening panes.

I have attached two photos. One of the top of the leaf and the other of the underside.
The topside look like very pale gold spots that go through to the underside of the leaf.

Thanks

Looks to me like the leaves have been scorched by the sun after getting water on them.

i may be wrong,but they look like water spots to me,used to get them when we lived in surrey,its the hard water i think,we are now up here,with soft loch water and dont get it at all now,dont water the foliage,water the ground beneath,when i did this we got no more spots,and unless you get storms,leave the g/house door open,mine is not closed between june and october,so there is never any stagnant air in there.i find the toms,peppers,melons etc thrive in these conditions,but we do miss out on something you dont....sunshine..so let them grow and enjoy..

scold spots,any water splashes,acts as a magnefier in the sun,and burnes where ever the water droplets are,you plants are not at risk of anything nasty,

Water/scorch marks would make sense.

Great photos - ever thought about taking photos for a horticultural book?

I agree with the others its scald/scorch, nothing to worry about.

Scald can occur without water drops on the leaves.

Phew!!! Thanks for those quick answers.
As for the photos, I took the leaf off the tomato plant, placed it on a piece of paper, scanned and saved it. :-) If anyone would like to use these photos, let me know. They can't be found anywhere else, I know because I've searched!!! :-)

I've been leaving the greenhouse door open 24/7 now, and although it's only been a few days, the plants look better and the air inside is "fresher." Thanks for the tip. I was only leaving it open on very warm days.
