Advice needed for wrinkly dendrobium nobile (noID)

[flowerpower]

Got my Dend nobile NoID on June 20th (in bloom) and immediately repotted it. It was potted in some kind of soil type mix so I carefully removed it all and was pleased with the roots. Firm and wiry roots. I repotted into a mix I had from Orchid Focus (dry bark and coconut husk type mix). Unfortunately I was in such a hurry to get it out of that soil I did not have time to soak bark. Straight away the flowering cane wrinkled and the older short cane wrinkled too. There was a small new shoot growing at the base when I bought it, which is continuing to grow, and it has even decided to start a second new cane at the bottom, 1cm high now, which I was delighted to find!!!

I don't know if I should really step up the watering as much as people say they need (eg daily), but when I saw the wrinkles I did soak for several hours to no effect. It was watered yesterday and there is still moisture in the pot and it's in the evening of the next day, just doesn't look like it needs another watering today? I don't want to rot the plant with all this watering. I was in the store I got the orchid from recently and the other ones are not wrinkled even though they don't get water or any light!

Find below before and after shots, the canes were plump when I bought it and I'd really like to make them plump again.

So should I:
- do nothing, this is normal dendrobium behaviour, continue alternate day watering
- step up to daily watering now it is the growing season
- soak the whole thing again for an hour
- repot again in a finer mix for added moisture?
- reduce watering?

Just to reiterate these wrinkles seemed to appear rapidly after repotting and then it remained stable. No pleating on new growth (which is putting out its first few roots now (very short).
