I just got an order in from HHV and the two 15ml bottles I ordered at 24mg strength. Recently I haven't been putting nic on my liquids since I am messing around with new mixes and don't want to waste. I normally vaped 24mg but now it seems too strong. I have both pg and vg, can I simply add a bit of either one to dilute the strength? If so if anyone can help me determine the amount I would be ever so grateful. I would like to get it around 16-18mg total.
