Weaning at 4 months

I know there is alot of debate about whether to begin weaning before 6 months or not. Every baby is different. I feel my little boy is 100% ready for something other than milk. It just isnt satisfying him as it should. So my question is other than farleys rusks mashed down, and or baby porridge. Is my 4 month old allowed blended fruit/veg?
