What's wrong?

[Ger-annie-um]

I grew some lovely caulies, overwintered them, they were really healthy plants until.........I noticed a few of the leaves looked as though they had been scorched. Now that would have required some sort of miracle because this was a good month ago and there was no sign of the big yellow ball at all. Now my calabrese seem similarly affected. First the leaves start to go pale at the edges and then they start to look crispy and dried. I checked the roots, they looked fine and I removed affected leaves and repotted but it's made no difference. Any ideas?

are they behind glass,if so the weak sun could maybe the culprit,if the centre growing bit is ok,they should be fine,give them time and see.
