Cant see really. Take a pic of the plant from the bottom lookin up to the top... If ur plant has something looking like little banana clusters then its a male. If no clusters then u have ur self A BABY GIRL.
It seems to be a fine line between genetics and deficiencies... best bet if ur wanting colors of any sort it would be best to keep temp between 65-70. Anything more is up to the plant.... good luck....
I got this purple gorilla I cant seem to find mutch info on other than its mother was a strain by the name purple rainforest, (which my husband and I think is actually purple rain) but anyways it stays purple through and through and has an overwhelmingly strong grape smell with a slight rotten...
