Candle Seconds

Back in high school I made a lot of candles using paraffin wax. I recently started playing with candles again, but wanted to change to soy wax. Soy wax is more earth friendly and I love its rich creamy color. I bought some wax that is 100% soy and is a one pour type since soy wax shrinks very little as it hardens. However, I have been experiencing issues with blooming or frosting. The candles that I pour start getting white or discolored in regions a few days after I pour them. See the mocha candle pictures below. I can't figure out what I am doing wrong...any suggestions? I may just need to get some Ecosoy advance wax which does not appear to be 100% soy, but it also does not bloom as far as I can tell. I have had a hard time finding information about making soy candles. All the books I have bought or got from the library on candle making either do not talk about soy wax or they only have a page about it. Any suggestions would be appreciated! :)
