Funny you should comment Ruth! I was just examining them today; they look exactly the same as they did a week ago, no taller (not spindly) and the leaves are quite thick for seedlings and are now going bronze at the tips so possibly not long to live. The lights are actually closer than I usually put them when I use my light garden, and I had a dome on the seed tray until a day or so ago. I have been growing the seeds from the same packet for 4 years now so perhaps it is a problem with the age of the seed - young enough to germinate, too old to do much more
