Hello

I have a slightly odd situation. I have around 30 tomato plants growing outdoors that are all doing well. Plot neighbours on both sides also no issues with their plants.

In my greenhouse I have 6 'mature' tomato plants. 4 of which have provided ripe tomatoes already (2 unknown varieties, green zebra and an Oxheart variety. The 4 that have provided ripe fruit have what looks like could be blight to me, the other 2 are ok. There are no marks on the stems or tomatoes themselves that I can see and top growth seems ok so I'm not sure. The plants are in pots with bought compost and I've only fed them once so wondering \ hoping if this could be nutrient deficiency. First time growing in pots and a greenhouse.

I have some smaller later tomato plants that are all unaffected so far and look much healthier.

Doesn't look like blight - once fruit has formed it's recommended to give a specialist tomato feed once a week, which should contain important trace elements which may be in short supply in your pots.

When the leaves start to die off it's best to remove them - they've done their job and you don't want decaying vegetation hanging around in your greenhouse.

Thanks JayG - I've definitely not been feeding enough as you say, I cut a fair amount of leaves off yesterday but will chop the rest and see how they get on.

Only remove the dying leaves - the plants need the rest of them!
