algarve,
Portugal 
my first time growing tomatoes "roma vf" have round darke patches at the end, first I thought an insect or other animal does this, but now I'm not sure, also they are very small. Can somebody tell me what I've done wrong ? Too little or too much water, or ..........

Thanks for replying, they are in open ground and now I started watering them twice a day, because of temperatures in 30ºC, hope the other new tomatoes will be ok. I'm feeding "biorgano" which is a granulated multi organic stuff, but don't know how many times I have to put those.
kind regards,
marleen

it sounds like your tomatoes have got blossom end rot , this is caused by letting the compost dry out.Are they in the greenhouse and do you feed them.?
