Are there any inherant problems with forcing flowering early? Plants are only 10" tall but the main stems are already 1/2" thick at the base. Time is an issue.
It is not too early to put your plants into flower 10 inches in heigth is great. I put this last grow into flower whe they were about 5-6 inches tall. Thye will double to triple in heigth during the flower cycle. Good luck
