@trenbania Just to make sure, are the fields ‘scientific_name’, ‘family’ and ‘scientific_tree_family’ assigned to the post type you’re pulling in via the relationship field? And those fields are not in group field or repeater? You shouldn’t have to but may need to pass the post id when retrieving the field values.
Maybe try:
$posts = get_field('info_from_growing');
if( $posts ) {
foreach( $posts as $post) { // variable must be called $post (IMPORTANT)
setup_postdata($post);
$id = $post->ID;
$scientificName = get_field('scientific_name', $id);
$family = get_field('family', $id);
$scientificTreeFamily = get_field('scientific_tree_family', $id);
// do something with the values
?>
<div>
<p>Scientific Name: <?php echo $scientificName; ?></p>
<p>Family: <?php echo $family; ?></p>
<p>Tree: <?php echo $scientificTreeFamily; ?></p>
</div>
<?php
}
}
