The plant in bud will probably stay that way. Enjoy your bonus... The one with no buds will go off on schedule. The other two all depends.... If the plant is bolting, she will go off, in Aug/Sept but the bottom small buds will elongate out and become worthless. They will turn into branches and bud as expected

If the plant is slowing down it will soon go off. You don't want that to happen now. Far too early. Lose a lot of yield and the flowers will not be tight.
