Agreed. Wait a couple weeks.Its not showing signs of sex...or just cant tell from those pics.
Hmm I've been vegging for 5 1/2 weeks if you look close on the pic of the internode you can see a very small ball looking growth these are growing on almost every internode just a little worried about it
The only thing I can add is I've been told that all blueberry strains well hermi on ya. I have grown skunk blueberry and the 4 that I grew did. I don't know if the hermi thing is true or not. Could be just me.
