I dont know if it is a hermi. I didn't really see you describe it as a hermie. Did you mean pollen sacks not resin sacks? Well if you sure it is hermied then no, you dont want to keep it. It will seed your true female and ruin the bud. They only way I'd keep a herm is if I was a week away from chop and I didn't have newly flowering plants in the room. It takes about 6 weeks to make viable seeds so its not like it will grow seeds in a week. With plants just starting to flower it will make a bunch of big energy sucking seeds and will kill you harvest. They only thing youd want to keep it for is pollen, but since it hermied right off the bat with minimal stress, you wouldn't want to pass those genetics on anyways.
