Polar_lace, that Jacks classic stuff is realy good stuff, as its basicly simular to a very good general fertiliser we have over here in the Uk.
Its got all the same trace elements in it as ours- its the Boron and Molydynium and zinc, that tomatoes seem to realy like.
Next season- I am going to try what Craig suggested and put all my egg plants into large pots- together with a good dash of cow manure mixed in.
