hmmm looks a bit like it could be a hermie although it looks like there are female pistills coming out of the balls. it happened to 2 of my DP blueberrys but this is normal for blueberry to do sometimes.
i did notice that on my blueberry most of the wot looked to be male flowers actually turned into female an jus ended up with pistils flowering from them.
id reccomend waiting for a week to see if this happens if it does then good but. or you could jus remove them an see if it continues to flower normally thats wot i did after a week as some balls were still left
if u do remove them keep checkin yoiu dont get anymore
good luck i hope it turns out female
