Our first tomato to ripen (i a growbag in the greenhouse) has got blossom end rot. Is that due to ove or under watering?
I think the jury is still out on that one-one theory is it is a sign of irregular watering-or letting the plants dry out to the point where they are wilting and then giving them a soaking.
Italophile will hopefully add a bit more-I think there are a few other theories
