Cut them galls off, they suck.
The very leaf tips are dying back a bit and yellow.
The remainder of the leaf is a little spotty for yellow.
Looks like either an over fert job and burning perhaps, over watered, and perhaps a nutrient deficiency.
You said these were transplanted, do you know much of the history, like were they plonked in with a handfull of fert etc?
I know this is contraversial but here's a link to a site I googled showing many examples of the same thing.
