Looking through the microscope I occasionally see a long thin white string? There will just be one or maybe two on a bud. Is this some kind of fungus? Could it be a cat hair? I can't see it with the naked eye.
Hi, it’s mostly likely cat hair, looked at the 2nd pic in your week 11 and can see cat/dog hairs.
My first thought was it could have been webbing from mites, however, I don’t see any signs on your leaves so can’t be that
