diagnostic help for 'frosty spears'
First time posting to the sans forum! I am glad its here... I have a sans 'frosty spears' that I got from gringsby ages ago. Its finally doing something (growing, that is) and I find these strange symptoms. It looks as though the older leaves are turning white! It has been summering outdoors since June, in pretty good lighting. Any ideas?
