toms flowering but very few fruit

[Bitzy66]

Hi all ,I was wondering if anyone can help ,I have Romas and Gardeners delight in the unheated greenhouse ,they are flowering like mad but after a while only a few fruit per truss has formed perhaps 2-3 , I feed them once a week and have got them in a ring with the compost then into sand /gravel mix
I have been treating them for what I thought was magnesium deficiency ,any advice would be appreciated .
Thanks Bitzy

Give the plants a good shake every time you go into the greenhouse, that should get the pollen distributed, Bitzy66. And make sure the atmosphere is not too dry.
