chop her, your safe to harvest, esp. if your having problems with mold and bug issues, be sure to check everything for mold as i know you will.
if you keep her for another week you may lose out on some good thc as well as getting more mold going since it will rain for you, i think i would rather harvest now instead of trying to go longer, in the end though if you were to go longer the bud will be more couch locking, is all your buds will not double in size waiting the extra time, usually i would say wait the extra week out, that is if you did not have problems esp. with mold,
like i said i would chop as the other option of getting more mold and could ruin my harvest. hope this helps
