Tomato leaf problem

[chrissy67]

Could anyone help with this problem with the lower leaves of my Tiny Tim tomatoes?





I have been growing Tiny Tim and Red Robin tomatoes and last week transplanted them into 2 Chilligrows on my south-east facing window sill. The Red Robins are fine with no sign (yet!) of the same leaf spots.

The leaf above is the worst affected but there are spots coming on some of the lower leaves on all three plants.

Any advice would be welcome as I do not want to bin them if they can be rescued as they already have flowers coming!

They look like they may have gotten water on the leaves in high sun (baked). Sometimes a little splashback is enough to do this. Try only watering in the evening when the sun isn't directly on them ��

To me they look scorched, like the leaves have got wet and then sat in bright sunshine. How have you been watering them?

I'd tend to think it was maybe that the compost you've potted them into was maybe a bit nutrient rich or that they've got a bit heat scorched. A view of the underside of the leaves would be helpful though just to discount fungal or pest problems. Plus, maybe a picture of the whole plant and pot and info about when you sowed them.

In the meantime, can't see any need to bin them.

Thanks for your suggestions. Here are another couple of photos



The seeds were sown in the middle of January and the plants were kept under lights until the light levels meant they could go on the windowsill.

They are only watered from the reservoir in the Chilligrow so any water on the leaves would be from condensation.

I cannot see any pests on the underside of the leaves so I hope it is sunscorch rather than a nasty disease. Searching on the internet flags up some horrid viruses and I thought asking here would calm my panic!!

I used to panic like mad every time the slightest blemish showed up. I'm a bit more relaxed now. Yes, some plants do get diseased, like tomato and potato blight later in the year. But at this time of year, it's more likely to do with growing conditions than disease.

I wouldn't worry about these blotches. Sun-scorch is the most likely culprit. Maybe some water got on the leaves of one group of plants when you potted them up. Either way, all looks good to me.

The Tom on the right in the photograph is smaller, but looks really healthy and bushy.
The other 3 look a bit leggy and in the sun.
I would suggest either shade those 3 or move them out of the sun.

I can't see how they can get burnt from the sun in this weather unless they were burnt while under lights? Have you let them dry out too much on occasion?

I agree with Fishponds that the three on the left are a bit leggy. If they already have started flowering I would be tempted to stake them. They don't look sturdy enough to hold fruit.

Like Snoop, I'm pretty relaxed about leaf marks, especially on older leaves. I wouldn't worry about those. Maybe the after effects of being potted on and moved to the window?

[chrissy67]

I have staked the leggy ones now, they are supposed to be bush tomatoes but I have my doubts. The one on the right in the picture is a Red Robin and that is robust, bushy and very healthy looking. I have treated both varieties exactly the same, sowing, potting on etc at the same time.

I have not grown either variety before so am looking forward to finding out how well they perform.

Thanks for the advice and reasurance from all.
