Thanks Nut, it has been in the ground for a couple of weeks now. At first I thought it was stress of planting.
Thanks Pete, I don't think it's sun as keeps on coming regardless of sun or not. Ive looked at the stems, the upper ones with leaves are fine. The lowers mainly ok but just a couple of round spots of black. I'll post a photo separately. (I note you aren't an expert but appreciate experience and ideas!).
