Trees, Shrubs and Conifers: Yellowish sickly Nandina, 1 by pennefeather

I planted three dwarf nandinas about three weeks ago. Two seem to be a nice healthy shade of green, but one is significantly lighter - yellowish. The three shrubs all appeared to be healthy when I planted them. They are within a couple of feet of each other. Before planting them, I had already amended the soil with compost, and planttone. Since noticing the color, I have given them some alfalfa tea, in the hopes that this would help them to green up.

I have also tried looking for insects on the yellow nandina, but didn't see anything. The leaves don't appear to be wilting, and all three are watered regularly. I am stumped as to why it look like this. I would like to take action as soon as possible, because I don't want to lose this shrub.

This is the sickly nandina.
