Im a bit worried about my tomato's..i managed to overwater them in recent weeks and they're curling up around and down and all sorts of different ways. i had a look today and some spots have appeared on the leaves of one plant. and another has discoloration and a brown patchy/spot on the lower leaves, maybe you guy's can help diagnose.

I've found a thread shoing similar symptoms to my tomato plants. it looks like i have overwatered and i did feed once with liquid fertilizer...but im not entirely sure what i should do at this stage.

I wouldn't be too worried, the lower leaves in particular on my plants go like that every year, doesn't seem to affect the crop in any way. Just don't water them for a bit, but keep checking to make sure the soil doesn't dry out, and when the plants are 2 or 3 feet high you can cut off the lower leaves to improve air circulation. I hope this helps!

thanks for the reply..just for the record..plants are already 3ft high!! 4 trusses formed already..i must be more cautious with watering in future.

The yellowing of the lower leaves points to a deficiency of Magnesium, which can be prevented and cured by the addition of Magnesium Sulphate (Epsom Salts), one teaspoonful in a gallon of water and applied at the rate of one in 100 once a week. Magnesium is easily washed out from soil especially light sandy soils.
