Flavor just dies after a few vapes.

[Ragman]

Ive been messing with DIY for awhile and one thing Ive noticed is that my DIY flavors only last a few puffs when dripping. I still get plenty of vapor 10 to 15 puffs in, but flavor just dies after 3 or 4 puffs. Those 3 to 4 are good but WTF? anyone know why this is?

Just to give you an idea of a basic recipe that does this.

3ml mix - 1.5ml 48mg VG
.5ml VG or PG
12 drops PGA
20 drops PA - Caramel Candy
8 drops PA - Cotton Candy
5 drops PA - Caramel (mapley)

Try putting a drop of the PA Caramel Candy on your atty after the flavor dies and see if you can taste that?

This seems to happen to a lot of people, usually it's temporary. I have no idea what the cause is, but I'd say it's hardware or your tongue since plenty of people use the same flavors you do but don't have that problem.

Im thinking the culprit is my VG. The last batch I made was with nic-VG and plain VG (I cut 48mg to get to 24mg) Im gonna try the exact same recipe with just straight PG (I dont have any PG nic) and see what happens.

As you said, VG could be the culprit. For awhile, I started mixing 30/70 VG/PG and discovered that I had to increase the flavoring t0 15-20%. I am not sure if the sweetness of VG overwhelms the flavorings or if it is something else.

Now that I am back to a 20/80 VG/PG mix the flavoring is at 10% again.

I have a feeling the VG condenses ever so slightly on your tongue and coats the taste buds a little, dampening your ability to smell/taste the vapor. It could be tested by vaping plain VG a little first, then switching to another atty with 100% PG liquid and vaping that. Any volunteers?

I go back and forth being able to taste my vape and not. I do notice that 100% vg mixs give me this problem more often though. AND I'm trying some diy with the vg i got from walmart and having problems getting the flavor to come out as well..

... I believe that also explains the feeling of creaminess folks talk about.

This might explain why I end up using higher than expected proportions of flavor in my mixes; I use mostly VG. The only PG I get is what the flavor is based in. This is kind of a catch-22 since I'm trying to reduce the harshness of straight PG liquids at high voltage. I think I'll try a 50-50 VG-PG base to see if that makes any difference in how much flavoring is required. Interesting subject.

I'll also try PV's idea and switch the same flavor to 100% PG and see what that does. I'll use the same ratio of flavoring to see what happens. I'll try to do that this evening.

For what it's worth, I haven't yet experienced the issue of fading flavor.
