I had to look back at your original query, if you want to respond to this, click in the box below my comment and type it in there instead of posting a new 'Question'.

I forgot to say something - you've said its growing in a five gallon 'bucket' and I forgot to ask whether there are drainage holes in this bucket. That's very important, and assuming there are, increase your watering - its better to have more water which can drain away than not enough, which might cause the flowers to drop off.
