You might be having light leaks.
Go inside your grow room at lights off and hang around 5 or 10 minutes and see if you can see ANY little pinholes of light .
Even the smallest pinhole can be enough to cause one to go hermie on you.
Might be some other form of stress on your girls, but this would be where I'd start lookin' first.
Hope this helps....Welcome to the forum.................J
