Hey all! well i am almost 3 weeks in to vaping and LOVE it! i have a couple questions i am hoping to get help with ~ 1. my KGO came with 2 empty cartridges (no filling) and a couple of cartridges i've used heavily have filling that looks pretty grim. is there a filling i can add to my empties and to replace my worn out ones. i use my cartomizers quite a bit but i seem to get more solid toots from the cartridges and i don't mind adding the liquid more often. ~2. i have been using Hoosier to this point and actually have been very happy with their Dekang- USA Mix, Vanilla and Caramel. they are all 100% PG and after trying a 60-40 mix of another brand which i really enjoyed i'm wondering can i simply add some VG to my Dekang 100% PG? i really enjoyed the vapor of the other mix and it was a beautiful throat hit. Hoosier has the Dekang 50mls @ $11.00 which is a steal and would it would be awesome if it was just that easy to add VG or mix in other flavors. thanks in advance to all you guys and gals that take time to help out us newbies! Cheers!
