Tomato Problem?

Hi everyone.
Iâ??m new to the forum and to tomato growing. I have six tomato plants in a greenhouse in 12â? pots with gravel filled trays underneath. I always make sure each tray has at least 1â? of water in it. The pots contain general purpose compost and I have been feeding the plants with tomato feed as to the manufacturers instructions. I have two varieties growing. Legend and Ferline. (both blight resistant) I noticed a problem with the tomatoes on one of the Legend plants and have taken a few pics. I was wondering if anyone more experienced in tomato growing could tell me what this is. I thought maybe BER or severe catfacing?
Thankyou in advance to anyone that can help.

 

That looks like blossom end rot to me. I don't think it's blight - I take it there is no sign of blight (dark patches) on the stems and leaves?

BER is caused by a lack of calcium. Instead of having them constantly sitting in water, maybe try to water the plants little and often so you get a regular flow of water through the pot, which helps it take up calcium.

 

I would second AndrewH and say BER.
I always find it a problem with the bigger varieties of tomatoes no matter how I do the watering.
For that reason I don't grow jumbo tomatoes anymore. The smaller varieties never have the problem.

 

Many thanks for your quick replies. Is there anything I can do to sort it? I have a box of garden lime in the shed, I also have some pure calcium carbonate powder as I use it for my reptiles. Will either of these help?

 

It's probably due to overwatering, which stops the plant's roots from taking up the nutrients, Maytree. It's unlikely your soil is lacking calcium, especially if you are feeding.

Instead of having them constantly sat in water, start watering them little and often.

 

First and foremost, take them out of those trays, you don`t want them standing in water.:gnthb:

 

I can see blossom end rot in the pics, but after looking up both ferline and legend I cant see anything that looks like that.
The tom on the right in each pic looks normal to me, but only for something like marmande that grows that strange shape and seems to have double flowers.
