I also ordered both Blueberry and Big Bud seeds and never got em after like 120 days of supposed multiple "reships" and "whoopsies" fixed. Finally got a refund after harassing the shit out of them on multiple sites and showing folks proof of how I was being dealt with. Never again. The whole story can be dug up on the web I'm sure. I was providing links to pages of hoards of people who didnt get their orders after Robert saying that most everyone was getting their orders which was total BS. Then when I shared the link to these multiple pages of unhappy customers they tried deleting my comments and changing the links on their page from forum to forum in hopes that nobody would see it. They finally had to address me and the hundreds of unhappy customers who had sent money to them and recieved nothing. They were denying issues and werent giving the promised refunds or reships until someone put them on blast. I helped a lot of people get their money back and get reships. Its amazing how tenacious I can be when I've been fucked multiple times.
I honestly couldnt tell ya but I will say that most bud swells up considerably in the last 2 weeks of flower. Light intensity/pruning/techniques and environment has a LOT to do with yield. Looking at your pic, it looks like you got a ways to go time wise. They still look quite young but they look great!
