Blossom end rot on all Black Icicle toms

[Babru]

First time growing Black Icicle tomato. I had an earlier question about how droopy the plants were, but apparently this is normal with this variety (though they do look like they're about to expire).

I have been picking Sungold and Gardener's Delight for the past couple of weeks now, but every single one of the Black Icicles forming have had black rot at the base I've taken this to be blossom end rot and removed them. As none of the other varieties have had a problem, any suggestion what I might do about this? Is it a particularly susceptible variety?

All the plants are in quadgrows, so the watering is totally consistent.

I had a few on my first tomatoes , and there in quadgrows too , i just gave them a little bit more water into the pot and when i feed the them i add a little bit to the the pot as well....it seems to have worked , no more blossom end rot .

Watering thoroughly seems to be the answer to most things like this. We also save our egg shells, nuke or dry fry them to help calcification (get some light browning). Then put them in the blender/morter and pessel. Take a good sprinkling and add to the hole when planting, add some more to the 'mixture' and a light sprinkling as a mulch on the surface. the calcium is supposed to stop Blossom end rot.

We generate lots of powdered egg shell and apply it to the greenhouse soil a couple of times a year to keep up the content. We plant direct into the soil. I know it can take a while to breakdown into usable form, some disolve the crushed shell in vinegar for like 2 weeks and then dilute the result about 20-1 and apply like a feed. We scatter surplus shell about the compost heap and veg beds because it can do no harm!

I am also growing these for the first time this year.
The foliage is definitely droopy.
Three of the tomatoes on the first trust had blossom end rot.
I have been giving the plant extra water and feed and they are all fine now.
Picking from the fourth trusts noe.
They are very flavoursome.
I did say I wouldnt grow them again but I am changing my mind.
Next year I will know better what to expect.

Thanks all, I've started watering and feeding them from the top as well as the base, hope this does the trick. Starting to despair you know, two out of eight plants producing nothing.....
