Hi,
I just noticed a black spot on my Cattleya rexe's new growth. It wasn't there yesterday when I repotted it, I just saw an area of a slightly darker shade of green which I thought was mechanical damage.

Should I remove the growth?
PS: The plant looks quite dehydrated because I did not water it for four days in the hot weather due to absence. I had this degree of dehydration before and it never hurt the plant if I soaked it right away (I did wait a day because of the repotting).
