Only found this article .

If I had seen it earlier I would have suggested that they have been allowed to get too dry!

I zoomed in on the pictures and would say four of them still had a growing tip the other two look like as if they have had it!

I would have also suggested that you give the four with growing tips a good soak in a basin of water until the compost surface had darkened then I would have allowed them to drain off in a bright but not in direct sunshine spot.

What has happened to them. .

 

I was a away for a week and the sun got to them
