Tomatoes - some fruit not growing properly

Afternoon all,

A small percentage of my tomatoes don't seem to be growing properly - the fruits grow in a plain shape, with dull colour and a bad taste. Any clues why this might be?

This photo is of two tomatoes grown on the same truss (Coir de Bleu variety I think). The one on the left was lovely, the one on the right went in the bin. I have had the same issue on other plants and varieties this year, and a few last year.

    How and where are they being grown.

  • In a greenhouse, in bags of good compost,with a constant supply of water from water matting wrapped around the rootball.

    The constant supply of water may be the problem - I find it better to grow tomatoes 'hard' allowing them to begin to wilt between waterings - I get well flavoured tomatoes with few problems (fingers crossed image).

    And I grow mine in a form of hydroponics, in 10 inch pots of compost sat on trays of fish tank chippings, where the chippings are watered not the pot, ensures the plants are not over watered.

  • The water is drawn up from a lower reservoir as needed by the plants and the compost is never damp to the touch so I would be very surprised oftset could be described as overwatered...

    I think the point is that if you give too much water you dilute the taste.

    But I am intrigued by your saying the tomato had a bad taste. In what way?

    Those two toms came off the same plant? Coir de Bue is an oxheart variety, the one on the left is pretty typical. The one on the right, from what I can see, isn't. Unless it has some ribbing on the shoulders (the underside in the photo), I think you might have had a crossed seed.

    My system is similar to the old "Root Culture system", where tomatoes in pots were placed onto a bed of chippings, but was a nuisance digging out the soil in the glasshouse, my way when the tomatoes are gone I have usable space, to overwinter tender potted plants.
