I think there might be some problems that would need a lab analysis but really I don't know of any. But, even if we don't cover every single problem a daylily could have, I still think it would be good to have most of the common problems covered with a lot more examples that are available on the AHS sight. Plus we could have all the other information you mentioned added, history of the plant, photo of the entire plant, and shots of the problem. I hope people will contribute their ideas and photos, maybe we can even lure some plant experts to take a look at the info presented and give some opinions.
