Good morning
My (from seed) M. Sikkimensis have taken a relatively sudden turn for the worse. They were looking a bit pale so I moved them into my conservatory prior to them being planted out later this month, I was just waiting for the current spell of wet/windy weather to pass before planting them in the garden (after hardening off).
About a week ago I gave them a feed of all-purpose liquid feed
Gro-Sure All-Purpose Plant Food | Plant Food | Westland Garden Health | Westland Garden Health and they seemed to be 'waking up' a bit - pushing out new growth but yesterday I realised they were looking unhappy with white stuff on the leaves and yellowing and blackening occuring (see images).
Is this mould from being inside/restricted airflow etc a bug, disease or something else??
Your help greatly appreciated!
