Skipping first row in a Loop

Hello, I have a loop that I am running but need a little modification to it.

Sub ErrorFinder()
Dim i As Integer
i = 0
rowz = Range("A1").Offset(Rows.Count - 1, 0).End(xlUp).Row
For Each Rng In Range("A1" & rowz)
    If Rng.Value = "" Then
        Rng.Interior.ColorIndex = 3
        i = i + 1
    Else: Rng.Interior.ColorIndex = 0
    End If
End Sub

I was wondering for this line of code:

rowz = Range("A1").Offset(Rows.Count - 1, 0).End(xlUp).Row

Is there a way I can skip the first row and still run the loop?
