Hi Steve, sorry I missed those yesterday. I agree, a lot of yellow ones. Large plants can be very difficult to establish compared to small ones. More possibility of wind rock, more leaves in proportion to roots.
Are they totally root firm and kept moist? (but not drowned) See what others think but I think this is more a case of struggling to get established than of disease. The affected leaves look like those that fall off all hollies but more of them
