Probably a male, but I would wait another 5 days because there are a pair of preflowers, one on each side in pcis 1 and 3. If another ball shows up on either side then it's most likely male. Female preflowers will not multiply as quickly as male balls and usually are only pairs on the lower branches for the first week. Those preflowers are too small to definitively say male or female, but looks like a male to me.
