Simple newbie pruning question

[VinesnBines]

If your soil is reasonably balanced, you should not fertilize young vines. You want to build a good root system and that means the vines need to work at finding nutrients. Fertilizer will encourage foliage growth. Although you want foliage growth you want roots more. If your foliage shows signs of nutrient deficiency, then you add that; an example is magnesium deficiency - the foliage will be yellow around the edges of the leaves. Then you only add magnesium.

Thanks for the feedback
What about newly planted young vines when growth is not uniform?
Some are half the size of others in the same soil next to each other.
Is there anything I can do to equalize growth rate?
Thanks
