I solved the problem by creating a php counter http://stackoverflow.com/questions/11869142/how-can-i-make-a-php-counter

column-block-# where # is 1, 2, 3, 4 etc. until the repeat ends. see code below.

// check if the nested repeater field has rows of data
        	if( have_rows('column_repeater') ):

			 	echo '<ul class="small-block-grid-' . $number_columns . '">';

			 	// loop through the rows of data
			    while ( have_rows('column_repeater') ) : the_row();

					if (empty($counter)){
					   $counter = 'column-block-' . 1;
					}else{
					   $counter++;
					}

				$content = get_sub_field ('column_content');

					echo '<li><div class="' . $counter . '">' . $content . '</div></li>';

				endwhile;

				echo '</ul>';

			endif;
