@JustWondering1 - According to Bill's Magic Vapor (former commercial eliquid maker and longtime contributor on ECF about DIY), to avoid having a mix being cloudy after it's done...make sure the plain VG is
the last ingredient you add to it. I found out several years ago that he's right. I've never had a cloudy mix since then, no matter what type of flavorings are in it.
ETA: That little hint, as well as many more, and many of his recipes are in his Blog that's still on ECF. Because all of his recipes have a high total flavoring % (17-30%, since they were used for commercial eliquids bought by recent new vapers with dead taste buds)...I usually cut each % in half and they're great.
