No, writing 'no ppte formed' is perfectly acceptable. You could also state the colour of the solution. Go on to www.edexcel.org.uk and download the unit 6 specimin paper and mark scheme. It shows you how observations should be written.

If I can't see that anything has happened then I'll just write 'No visible change'.
