Brugmansia yellowing

Hi all, please can anyone offer advice on my brugmansia? It's in a large pot in a very sunny sheltered spot. It has plenty of new growth and flowers but its leaves are stubbornly yellow - not mottled like magnesium deficient tomatoes but an overall sickly yellow. I've tried tomato food, nitrogen, BFB and Epsom salts, to no avail. The new growth is a bit munched - could spider mite be the cause? I'm reluctant to use insecticide but running out of ideas! Thanks ????

The best plan is not to keep putting different chemicals on the plant until you know what the problem is. As you're finding out it will just cause more problems.
If you want to check for spider mites, you'll need a magnifying glass. If you have a bad infestation, their webs will be visible to the eye. Look on the underside of the leaves near the leaf veins. If you see 2 big 'eyes' staring back at you it's the 2-spot spider mite.
A photo of your plant may help us come up with some suggestions as to what the problem may be

Many thanks Pete. I haven't chucked all of that on at once, but over the course of several months, though even
so I think you're probably right about not giving it enough of a chance to react to any one thing. I'm having trouble adding a photo - annoyingly it's gone out small and sideways!
Ive had a closer look and there's definitely some critter action - I'll track down a magnifying glass for a closer look!
I don't know the plants at all, but the yellowing of the younger leaves can point to an iron deficiency, so sequestered iron may help, but of course it'll take a while to work.
But it may not be that at all, maybe it's just not happy for some other reason. I've never had one or know anything about them I'm afraid.
Whatever the bugs are aren't helping but unlikely to be related to the yellow leaves

Brugmansia leaves tend to do that. So long as the new leaves are growing, the lower leaves go yellow and drop off. It is flowering so not all that bad. Carry on feeding with phostrogen and plenty of water, They do tend to be martyrs to spider mite.
Easy to propagate for next year...
