Tomato blossom end rot
 

I seem to have a lot of BER this year, it's normally due to irregular
watering but I use a programmed watering system so it's not that.

Can it be due to the hot/cold weather we have had during the season?

Anyone else seeing more than their fair share of it?

Yes, many of my greenhouse toms have BER this year - first time I've ever
had it. Touch wood the Gardeners' Delight seem to be okay, but the
Alicante, Moneymaker and Shirley seem to be affected quite badly.

There are two reasons why blossom end rot occurs, irregular watering or
it's a calcium deficiency. Ed

Agree.
Our new allotment plot has a low pH and whilst I limed the Brassica plot
heavily I didn't think about the Toms and am suffering with BER as the acid
soil (pH5.5) does not allow the plants to get enough calcium. Next year I
will raise the pH where the Toms will go.

I use an automatic watering system and if anything at times they were
over watered but never dry. I feed Wed and Sat with liquid tomato feed
so again this should not be a problem. I grow 3 to a grow bag.

This is what I have always done with little or no BER, this year for the
first time I have a lot of it. Temp in the summer have reached 40 even
with everything open, now they don't get over 23 or 24.
