Anyone ever seen this?
Two blue dream autoflower started the same time
One has blue leaves and the other green leaves
No, I’ve never seen that.
Pics would help a little. 
I have photos and the last ones were a bluey purple colour turned out fine it was winter time with lower temps they say colder temps give those colours
They are both beautiful just different genetics you know brother and sister will never be the same.
Looks like you pulled a blue phenotype! Those are sought after. Congrats!
Pics are up funky
I guess it just has a stronger Blue gene. Killer looking plant! Congrats
my (new) star of my blue dream ladies has bluish/purple top sugar leaves on her main cola but the others are green as can be like normal. the BUDS on the other hand almost have a blue hue in comparison to my other strains 
i figured that’s where the name came from. they smell SO good!!
Lucky you as none of my Blue Dreams have turned blue at all.
