Started out with a problem with curled leaves, now I have sparse leaves and tiny ones.

I gave it a boost of minerals but no changes. I see no mites but gave itvs good hosing off anyway. Suggestions?

May be Thrips

Thrips live on the undersides of leaves. Young thrips are oval, white and wingless. Adult thrips are winged insects, ranging from pale yellow to brown. These insects create holes in the leaves to access the plant's moisture and lay eggs in the holes. Thrips cause an angel's trumpet's leaves to turn shiny silver, interfering with photosynthesis and destroying the plant.

Extremely interested in Cheryl's comments. I live in central Florida. My Berg looked like hers with the deformed leaves. I gave it minerals and it recovered and had normal leaves. I returned after 10 week absence to see lots of flowers but very small leaves and sparse looking plant. I asked a major seller of Bergs and he has no clue - suggested fertilizing, but the leaves it has appear healthy and, there are no insects of any kind so rule that out. I was almost thinking nemotodes as a long shot.

I never got a real answer. In the mean time the tree has totally recovered. Thankfully whatever it was, it wasn't a permanent disease.
