I have had a little of that problem when I don't let the mother come back to full veg. Many of the mother plant I had would keep showing just a few female pistols even after coming back to veg. After I got them back growing in veg good then my clones did very well. Although it may of been your skin on the hut or maybe temps. What strain are they ? I did have one strain that auto flowered and would not stop for anything. Sorry I forgot what it was.
