I've been told to try to keep humidity at about 50%, much higher I risk powder mold.
The potential problem I have is low humidity, my grow room runs about 30-35%.
The question is, can it be bad/harmful to run humidity to low? Can it dry out the odor causing tricomes/oils resulting in a less potent flower?
For now I like the low humidity but am I harming my plants?

I have a problem keeping my humidity above 20% and my plants are doing good. Lower humidity during flower is better than to high. I think yours is good. I have also read that lower humidity causes the plant to produce more resin to protect the leaves from drying out. Other opinions welcomed.
