Tomato and pepper problems

[kizkiz]

Hi,
Hit my first problem this year
Tomatoes and sweet peppers planted and grown from seed
All were fine until last week or so

The Toms are in the greenhouse, but they seem to be slowly dying. The leaves look like they are scorched, then get worse and completely die. I can't believe it is scorch with the lack of any sun!



This is a poor photo but you can see how it spreads

And the peppers here, which seem to be going black

i'd say it was the other way round and getting too cold
you say in the GH but is it heated overnight ??
i cover my toms and peppers in my unheated GH everynight with fleece just to sure

Oops, missed that bit out...the peppers are in the house under lights and certainly not getting cold. It's also only the two out of 10 or so in the same area.
The toms are outside in the greenhouse, but it hasn't been getting below 10c since they went out (only twice, and that was about 9c.)
If it was the cold, would it keep coming back even when not too cold? I've picked all the dying leaves off and the plants are still affected

I had the exact same with my Tomatoes a couple of weeks ago on one of my windowsills. I think I'd made the problem worse by watering them from the top as droplets of water on the leaves magnify the suns rays (apparently) I've moved mine away from that windowsill and although the affected leaves have withered the new growth is fine. Hopefully if this is whats wrong with yours too they'll still be saveable.

That was my initial thought, as the other half did water from above. The trouble is, they haven't been watered that way since, and it is still happening to previously healthy leaves.
It's also only affecting the toms. Nothing else in the greenhouse has any problems, including chillis, sweet peppers and plenty of other plants

My Sweet peppers are still on the same window cill that scorched my Tomatoes and they are looking marvellous - so maybe they just aren't as susceptable as the Toms?

The tomato problem does look like scorch, see if they grow on ok.

with the peppers which variety are they? as some of my purple ones get that dark colouring on the leaves as they mature

I think they were called californian

I noticed the same blackening you have on your peppers in between the veins of a young ivy i planted out into a container a couple of months back. No idea what it is so would be interested too.

Post google edit

A quick google and reading some threads on chilli forums suggest the purple-black tinge may be sunburn

Like you said though, strange with the lack of light. But if they've gone from say your windowsill where the light would be more filtered to a greenhouse without hardening off i suppose it is possible.

They look a bit hungry too unless that's just the camera

2nd edit (must pay more attention)

Didn't read that the chillies are under lights. I'd say it could well be sunburn then, maybe increase the distance from the lights or decrease the time they spend under it. As for the tomatoes, they can be a touch 'sensitive'.

Maccabee you're a star. That would seem to explain the peppers.
Thanks everyone for replying....looks like i'll have to keep a watching brief ont he toms for now.
