Thanks for the reply, yes, I think it might be the liquids since it happened to my novo with 1.2 or 1.4ohm as well (which was totally fine previously with some 40mg nic salt 50/50 from dash vapes).
The current juice I'm using i bought locally in Vancouver:
Koil Killaz (ironically) - Assault
Crave - Moo moo
Both of these do have more flavour compared to the ones I bought from dashvapes.
Koil Killaz ... sounds about right then! I would use such flavours with a rebuildable setup then, that's what I do with Taste of Gods now, it wrecks coils too fast.
