Tomatoes

[Luci]

I seem to be having abit of trouble with my tomatoes that i have been growing on the windowsill.
They get to a certain size,(with their 1st proper leaves) then just decide to die on me
Do you think i am over or under watering them?

Probably! As to which - let the soil begin to dry out before you water again. Don't keep it constantly soggy. If you are getting green colouration on the top of the compost they are definitely over-watered. If it's constantly dry, then you are under-watering. Good luck!
