I grew a pink angel trumpet this year and I have a?

I grew a pink one and it was so pretty the first flush of blooms and then it started loosing its leaves but then it had a second flush and then it really lost it's leaves so I thought it was unhappy were I had it so I moved it and it is blooming now but the blooms are totally white! What happened to the color? Is it sick? It has gotten cooler here
Could that be the problem or did I ruin it some how?This picture was taken the first time it bloomed and my recent picture is on my other computer so I will post it tommorow.This is my first Brug and I am really worried about it.

Sometimes brugs lose their older leaves naturally. If you let it get dehydrated, a lot will suddenly turn yellow and they will drop. Also if you have spider mites, they tend to drop them. Brugs regrow leaves easily when the conditons are right.

Lots of brugs tend to get lighter in color in the cooler weather. Do not worry, next summer it will return to its pink color.

Thank you Kell I feel much better now.It had been really dry for a period here and I have seen no spider mites. I did water when it was dry but I guess I didn't water it enough.
