I took a lone clone of a flowering plant in my last grow and found it to root very quickly but like you said it kept producing pistils but eventually it bounced back into veg mode. then it died due to my neglect dun dun duuuuuuuuun. but I learned something in the process, cloning flowering plants is possible but I'll try to make that decision to clone or not to clone next time before the onset of flowering.But knowin me I'll be doing it again...lol...
