Amaryllis 2 of 3

Sorry, missed out of 1 of 3, that one has flowered and gone already, this one is flowering well and 3 of 3 has some good leaves but so far NO sign of a flower.

1 of 3 was the last one to be planted so I'm somewhat confused as to why it flowered first.

Not feeling too great just now, dark clouds are hanging over me
