So I have a coral glow and a banana.
My banana was sold to me as het Pied. She's typical spotty banana. I haven't seen evidence to prove het pied keeps the spots away. I've seen other het pied bananas with the normal number of spots as well.
BEL complex will reduce spots.
My coral glow mojave fire doesn't have a spot on her. (unless this last shed gave her a freckle I missed, lol) From the fire banana's I've seen, they can still have spots, but a reduced number. Mojave banana would be the same.
