Tartrate is a bit unusual for electroless nickel with hypophosphite, citrate
or acetate is more usual. Try (all ingredients are in grams per litre):

Nickel Sulphate NiSO4.6H2O - 25 g
Sodium hypophosphite NaH2PO2.H20 - 23 g
Sodium acetate NaC2H3O2 - 9 g
a touch of lead helps (dip a small bit of lead in the solution for 60
seconds, that's plenty)
85 C

Thank you! This resembles plating steel with copper by means of an
acidic
copper sulfate solution. BTW, any particular caveats to be aware of?
