Sounds like it wasnt a light issue, maybe genetics or some other type of stress. Maybe heat stress since you said it was in the garage, are you sure the temps are in check. You can get a hygrometer that logs and displays daily high and low temps.
Hi Drmc . I have sentinel controllers for climate. I used Dp seed feminized seed. I had hi heat in the start of grow period .I hope that was my issue. I'm going to start with new seed next week Thanks
