looks like herms to me. no use growing them out if there's anything viable left in the grow box. they will just pollinate them too. remove the herms and spray the walls and other plants down with water. it will sterilize the pollen.

any guesses as to why they herm'd? could be genetics of course if you got them out of bud. but any light leaks? any other stressful factors (nute burn would be last on my list)

GL, herms are a dissapointment because they show you bush before balls :S1:
