Blueberries need 4-7 years to really reach fruiting maturity. Before then, they don't fruit well. They will fruit some, just not as well as they will in the future.
Grapes also need a few years before they can really produce.
But, it may also be a lack of phosphorous or too much nitrogen. Adding some bone meal help with this to balance out the soil nutrients. It may also be an issue with sunlight. They need at least 5 hours of full sun to produce well.
