Most of the time,it's best not to dry hop for more than 7-10 days. I get great hop aroma from dry hopping in 7 days. Too long & grassy/vegetal aromas & flavors can result. Not sure about the chemicals you used in water conditioning. I have yet to try all the packets og Burton water salts I picked up myself...
