So I have had my itaste MVP for almost a month. And today I decided to do a rebuild on my iclear 30. After cleaning and rebuilding my tank I added my new juice which is a 50/50 PG/VG mix with 18mg nicotine. After letting the juice soak into the whick for somtime its harsh I mean way harsher than before I cleaned and did a rebuild I used hot water and made very sure to completely dry everything. What could be my problem? When I tried my flavor at the shop it had 0 nicotine levels. Could that be effecting my throat hit? Any and all advice is welcomed! Thanks for the time!
