When the first fruits begin to appear it is always a good idea to remove all leaves below the first truss so this should also help your problem. A normal tomato fertiliser should also be useful if you have problems with epsom salts or if you are organic then I believe comfrey leaves placed around the base will do the same trick.

Salts are nothing to do with 'organic'. They are minerals.

Look at the simple things first.

Are they thirsty?

Are they cold and wet?

It is a popular fallacy that you should water in the evening, after the heat of the sun has lessened.

Plants are like children - don't send them to bed with cold wet feet, they'll become ill.

sunnystaines, you say you are growing them in large pots. Tomatoes prefer the likes of a grow bag as they like to spread their roots.

Depends how large the pot is.

I normally grow in ten inch pots. It allows them to go deep as well as spread.

I'm growing tomato plants this year for first time. About twenty, all at different stages.Tomato plants like heat and light as well as water and feed. Adequate support too. I gave one to my sister (it's indoors on windowsill at 24 degrees c..some like it hot!).It has produced about 40 little tomatoes ..most are green at moment.All of my plants are outdoors (average temp about 10-15 c and are just at the flowering stage.(Glasgow). I hope weather get's better. HB

Have you been feeding the plants regularly? If you grow tomatoes in pots they quickly impoverish the soil/compost. To overcome this they need feeding with a tomato fertilizer, most expensive isn't necessarily best - I use Wilkinsons link" target="_blank">http://www.wilkinsonplus.com/bin/venda?ex=co_wizr-locayta&template=wz_locayta&pageno=1&perpage=10&collate=pdxttype%3Apdxtcolourn%3Apdxtbrandn%3Apdxtsizen&threshold=43&fieldrtype=type&termtextrtype=invt&typertype=exact&typekeywordsearch=keyword&termtextkeywordsearch=tomato+fertilizer&searchsubmit.x=0&searchsubmit.y=0">link text
