Blueberry Auto Fem (Violet)

7/20 Day 7. I seem to have a problem with root rot in my other two plants regardless of the water temperature being below 68 and having two medium size air stones in both containers. I’m going to try to use the Kratky method on this one and see if root rot starts. Before I started using air pumps and air stones, I just had my original plant in water with some room for air. No root issues at all with that plant until I put it in the bigger set up that has air stones. There was even a lot of light on the roots and I still had no issue.
