looks like the leaf twisting is going to start soon. classic trait of blueberry. and btw, most blueberry pheno's will NEVER turn blue or purp. the may keep a dark hue to the leaves, but for the most part have vibrant green and neon orange buds. would you like a pic? as far as providing for environmentals, temps in the 70's is ideal, so why lower them to the point of stress? seems counter productive to me.

you just keep doing what you do mark "thumbsup:
