Wow thanks! Ok so the recipe is a blend of liquid barn products.. cola freeze, menthol, misty mountain, pacific dew, maybe some "sour" and a bit of pineapple... i just threw them all in together to finish up the products i had a bit of each.. also liquid barn nicotine 48 vg base and vg pg 50% ratio. Ill be sure now to deal with the coils as adviced. Really appreciate.
What do you mean by "clogged up?"
Your ratio of PG/VG shouldn't make much difference to how fast you "gunk" coils, but the higher the VG the better the wicking needs to be. If your setup can't wick fast enough to keep up with you (and VG wicks more slowly) you'll wind up actually burning the wicking material in the coil a bit.
Otherwise, it's likely an ingredient in your juice. I don't know LB flavors very well (though planning on getting at least their VBIC and Pink Lemonade this weekend,) but if any of them contain a lot of sucralose that's likely to gunk your coils fairly quickly. Also, darker juices tend to contain particulate matter that can also junk coils. Is the cola very dark or very sweet?
Just to give you an idea of the effects of sucralose on coils... I've been moving much more toward using RDAs lately, and I mix almost all of my own juice, but I still use a Nautilus 2 with factory coils sometimes, and occasionally buy juice.
If I vape 30 mills of a regular commercial juice in the Nautilus with factory coils, even something like a straight berry mix, the wicking material in the coil will be _black_. OTOH I can vape berry/fruit juices I make until the coil starts to lose flavor (easily 90-120 mills) and the wicking material will be pure as the driven snow. The difference? I use the same flavorings juice makers use, but I don't add sucralose.
