You dont need to feed peas,or maybe just a one time application of a gen purp feed. Over feeding can harm pea and bean plants. 
Spuds like fish,blood and bone too

Regarding the spuds, how is it best to apply the Blood.fish and bone?  Can I mix it with water or just sprinkle on the soil(I did add some in teh whole that I put the spuds in first off)

Same here Mum, I did mine a month ago and they look great (touch wood!)

I use wilted comfrey leaves laid under the seed potatoe, covered with a little compost to prevent scorching to the seed potaoe. However a little fertilizer.. I use Vitax.. helps to boost the crop too. I also use growmore at the top of the potatoe mound when the plants start to appear, and also use water with chicken manure pellets (Disolved in my water butt.)
Works well for me, hope this helps.
