I know you don't want to hear this but it just looks like a bit of bad luck and a bit of a slump. He's struck out 13 times in the month which is right in line with his other months (11, 14, 9 and 9). I don't have monthly gb%/fb%/ld% numbers but the strikeouts (or lack thereof) show that he's making contact...he's just not having the ball drop in for hits. A Seattle fan might be able to give you a more in depth analysis of how he's looked at the plate but the stats show nothing more than bad luck and maybe a slight lack of authority. While Ichiro isn't a home run hitter his 0 home runs since the ASB might point to a little less power in his swing.
