Why did you switch to flower so soon? I don't think you gave time for your girls to recover from pruning/training before switching to flower. I think this caused the low yields
@IvyGrows, This one is an autoflower so I think it decides when to switch to flower on its own. That's been my experience over 20-25 autoflower grows. In most cases that happens 4-5 weeks into the grow but its not something I've been able to influence. I'm interested to hear how you do that.
