First year blueberry! Time for dormancy?

Hydro growers!

Im "wrapping" up my 2nd year season, not that it ever stops indoor growing 💡🌱💡

I have some seasonal plants now! Specifically, talking about this sunshine blueberry bush. Its the 6th bush this year i bought, staggered throughout as they slowly died one by one and i learned how to care for them in a hydro setup. Its my only one to survive, and now seems to be much happier.

I'm new to blueberries so I'm curious why the center is a different color than the newer growth. I cant tell if its the slightly cooler air and headed to dormancy, or a deficiency – as all 1st yr bb growers seem to be confused by. 😁🤣

My setup is in my garage and the door stays open most days from 6/7 am, recently hitting low 60s in am, to 75-80 daytime temps. I plan to stick the entire pot outside once overnight lows hit 50s so it has time to acclimate and head towards dormancy for winter.

Added a pic of my lower shelf w my tiny tims, bell pepper that survived a brush w death, san marzano, and spacemaster cuke for happier thoughts that every outdoor grower is actually wrapping up summer produce and we can keep it rollin'!

Im pretty sure ive fallen in love with blueberry growing and the entire shelf with be dwarf blueberries in year 3. I tried propping some wild blueberries this year but a vacation ruined it lol. Pics 5 and 6 are the wild bb patch ill go back to in the spring and propagate some the right way 💚

EC-2.4 – feeding on masterblend, with "secret" ingredient instead of the normal calcium nitrate ive come to find blueberries find is toxic.
