Hi
@Magichuusom ! Judging by the dramatical increase in growth since your last update, yes it seems your plant has started to stretch, her internodes become shorter, she will start blooming soon, you'll see the white pistils then. Now about your sick BlueBerry, I see 3 potential issues : root problems, pH fluctuations, or overfeeding, but can't confirm at 100%. Some zoomed pictures might help to diagnose your issue. Hope this helps, keep us up-to-date and happy growing!
