Hi all, I'm going to jump in here, not because I have anything to add, but because I would like to learn more. First: what is twin scaling? More importantly, if I'm reading correctly, some of you experts believe that this red or pinkish hue is not uncommon. If that's the case, then how do we differentiate between normal, healthy coloration and Stagonospora? Thanks for your patience!
