Hi I am new to Brugmansia this year and wondered if anyone could help me please . The plants flowered beautifully for ages. I did have whitefly problems for awhile and used a systemic insecticide also dishwash detergent rinse and I use a slow release fertiliser.. However now they have more blooms ( not quite opened yet ) but the leaves keep yellowing and falling off, even the small leaves. I know the pots aren't really big enough but was too worried earlier in the season if I moved them I would kill them off. :(

Do you think they are having a last flush of blooms and then some kind of dormancy or do you think they have something else wrong with them?
Any help appreciated.

Will post some pics
