Here is a small thread on it,
There a many more threads on it with pictures, just google “cannabis foxtailing” check them all for “Hermies” I didnt see any in the pics but just be on top of them and remove them if you spot them… It doesnt effect the smoke I believe, makes for great fluffy bag appeal though. Read up and think back and see if there is anything that you may have done to promote it. What I did I found out after the fact ,is that my temps went into the high 80’s to mid 90° for extended period of time along with giving them veg nutes for too long into flower… so temps and veg nutes too long caused mine… like I said its really not a bad thing… but it Does effect the density and tightness of the buds… which means it effects yield…
