If nothing else you can wash them and make some sweet bubble hash 
They probably wont get you very high a month early. Let them finish and I suspect there’s a light leak or a red light on in the growspace. The stress could have caused it too. I’ve had a few herms and it was always one of those 2 things @biggysmallz. I’ve heard of some strains that are prone to possible herming but Guerilla Glue isn’t one of them. I didn’t have a problem with one causing the others to have seeds but it can happen. The weed will be fine. The THC potently may be a little less but GG4 is high THC anyway so it should still get you plenty high.
Thanks everyone. I destroyed them and basically kept the colas (about two O dry)
It seems trying to smoke the flower will be pointless. I’ll let it dry and throw it out if i can’t find some benefit from it…cheers 
ps. The buds seemed to be herming aggresively from bottom to the top of plant…not sure if thats common.
