Yeah I think you're both correct, it's too acidic. I will certainly dig them up and hope that they recover as the one plant was just fantastic last year. I thin we got to the bottom of it, will update the post when I have the final outcome
Good luck with it. I don't know how big your bed is, or how tricky it might be to alter it, but better to do it now, before they get established too well, or fail more.
It's a place where beautiful isn't enough of a word....

@Fairygirl absolutely, I have just been out to dig all three up. Not sure if I will try to make the soil more alkaline or just go with plants that are more acid loving. Probably the latter. I can always put my hydrangeas somewhere else in the garden... unless it's all acidic... I hope not.
I suppose that could also be an option @amancalledgeorge maybe I shouldn't have added the manure. But then again, it wasn't an awful lot, just the standard bag from the garden centre in a fairly large flower bed. I really did think hydrangeas loved acid soil but perhaps the Annabelle is slightly different. It'll be interesting to see what happens to them now that they are potted up in 'regular' soil.
@young codger I did thought at the start that it might be chlorosis, looking at it now it might still be that? But would that not affect all plants in the ground in my garden? Because it's only the hydrangeas that are suffering (at the moment at least)...

But seeing those yellow leaves it's hard to believe. But may be a reaction to the manure being too rich.

Apparently it is often seen in vinyard soils that are high in limestone.

I acknowledge what has already been said about ph and the white one, and maybe that is inconclusive.
