I came back from a weeks holiday and all the seedlings were dehydrated and looking very sick. I was using RO water and only giving additional calcium so I think it was a magnesium deficiency. I changed the feed and put the last 3 surviving plants outside yesterday. Feed with Greenhouse Grow + Hombolts Golden Tree.
