Grapes: Small Leaves and Closely Spaced Buds

[Brian2412]

I planted 7 different grape vines this spring with various results (Chardonnay, Cabernet Sauvignon, Merlot, Pinot Noir, Riesling, Sangiovese, Tempranillo). On a few of the grapes, the leaves were very small and now that they've fallen, the buds seem extremely close together (specifically: Riesling and Sangiovese).

Can someone tell me if this is a characteristic of this variety? Is there anything I need to be concerned about because of this growth (i.e. is it stunted due to some nutrient deficiency?)?

My soil is very sandy (QuD) and Alkaline. I planted a little late (April/May) and am training these to a single cordon. The Chardonnay reached the top wire (5 1/2 '), but the others did not. This is Washington Wine Country, so they should grow well here (Richland, WA).

Thanks for the help.
