I agree with @edhelka ... I never feed tomatoes until the first truss of fruit has set ... but I do grow them in good quality compost which will have some general nutrition in it.
Then when the first truss has set I begin feeding with a fertiliser high in potash to encourage flowering and fruiting.
Feeding before this only encourages a lot of leafy growth at the expense of flowers and fruits later on.
