Thats what I want to know... I've trimmed her back, root trim ect... and she is under one side of 240w of 4ft. tube floro's... I've never been a regular clone keeper... only in the past year or so... maybe the bulbs need re-placing- what I'm gonna do is try and go 20-4... snap her out of it, maybe... if not 24/7... I think gradually increasing the light would be more natch... anyone ever had this happen-??? ... peace. F1.
