You can try:

<?php
global $wp_query;
#$paged = get_query_var('paged') ? get_query_var('paged') : 1;
$args = array(
	'posts_per_page' => -1,
	'post_type'		=> 'groeiprocessen',
	'fields' 		=> 'ids', //not sure what to add here
	'post_status'	=> array('publish'),
	#'paged' 		=> $paged
);
$wp_query = new WP_Query($args);
if ($wp_query->have_posts()) :
	while ($wp_query->have_posts()) : $wp_query->the_post();

	$post_id = get_the_ID();

	$datetime1 = new DateTime();

	$datetime2 = get_field( "datum" );

	$difference = $datetime1->diff($datetime2);

    $verschil = "difference " . $difference->days . " days ";

	update_post_meta( $post_id, 'datum2', $verschil );

	endwhile;
endif;
