I've got one of those diagnostic apps, but each time I do a picture, it gives a different diagnosis!
First time, it said it had powdery mildew but it didn't fit because you can't wipe it away at all. I've tried really hard to scrub it with my nail and you can't get rid of the whites stuff.
The second diagnostic said it was a perfectly healthy plant. Well done. Keep up the work! Clearly this is not the case.
The third attempt said it was mites, but there is no sign of a single mite at all whatsoever. Apparently they're meant to be orange and should be possible to view, especially considering every single leaf is affected.
The fourth diagnostic said it was great and healthy.
So, I turn to Mumsnet! I have no idea of the history of the plant because it was given to me today. I have isolated it from any other plant in the house (upstairs where there are no other plants) and need to know what to do!
Any ideas would be gratefully received
