Usa zone 6, purchased some blueberry bushes early spring and we are still on the cooler side 50s-60s temperature wise reddish tint appeared in the leaves, added some blood meal on top thinking it was a nitrogen deficiency and have watered a few times since. Anyone know what this may be? Also fyi I have them under grow lights in a basement in cooler days and out them outside on the warmer days.
