Tropicals & Tender Perennials: My Hoya leaves have changed color., 1 by ah_hoya

I have 3 identical Hoyas all were root bound in very small pots.
A few months ago I repotted the largest one and I'm dismayed at the result.
The other two still root bound Hoyas are growing vigoriously sending out branches and both are a dark rich green. The repotted Hoya is not growing and the leaves have gotten much lighter in color, not sickly looking, but very noticably lighter.
I would like to repot the other two but I'm a little concerned.
Any thoughts.
The picture is from before I repotted.
