Some additional info on 'Sancerre' - this is what the bulbs looked like the day I planted them (5th August). In the pot, 'Sancerre' is at the top, and 'Corsica' is at the bottom:
The double-nosed bulb emerged first. The first nose emerged on the 19th of August (interestingly this appears to have been the shorter of the two on the bulb when it was planted); the second on the 24th (it is the second that shows the blotching on the leaves).
24th August:
2nd September:
8th September:
Looking back at the photos, I can see the distorted top on the shorter 'Sancerre' was noticeable on the 8th and hinted at on the 2nd. Some faint blotching is visible on the taller 'Sancerre' on the 9th.

The only day I can think of that might have caused this was the 24th of August, where you can see a local minimum of around 4 degrees (it was probably cold overnight).
Thoughts?
