… forking this off from my flower thread …
Mine very much has the deep blue-green leaves – like “that’s got to be a deficiency” blue/green leaves. But your old one didn’t have little leaf quirks? I could have sworn I read that this was a Common Thing™ with Blueberry, but I guess not 
I guess each breeder has their own variation, and DJS opted to go with the Odd Mutation variant? 
It’s a bit unsettling, isn’t it? Not all leaves are quirky, and I see no sign that it stems from deficiencies, pest, or disease: only the Blueberry do it, all Blueberry do it, and they’ve done this both while soil-fed and bottle-fed. But they’re happy and healthy, so I’ll let them do their thing.
Anyway, your Blueberry look obscenely chunky and delicious – I can imagine why it’s your favorite of the moment. If mine turns out anything remotely close to that, I’ll be a happy camper indeed
