Leaking through coil (GeekVape Aegis Boost Pro, B100)

[NapoleonHungary]

First of all, I am not a professional, I started vaping in the summer. I saw a good review about the GeekVape Aegis Boost Pro and I bought it in the Czech Republic. I was absolutely satesfied with it I was able to leave cigarette and change to vaping. However I noticed that my device is leaking through the coil. I thought that it is normal but the display began to malfunction thus I asked GeekVape's customer service for advice. They didn't even tell me how I should prevent or fix it, they immideately sent me another one because my warranty hadn't expired. I thought that my device was faulty so I didn't bother with it. My new device arrived and after a month or so the problem occured again. I asked Geekvape's customer service again but nothing. I checked a lot of forums regarding leaking through coil: They mentioned faulty coils and using too low wattage or bad liquid pg/vg ratio.
I think coil is okay, currently I've got 3 coils (2 from the kit, 1 that I ordered from GeekVape), I think it is quite unlikely that all of the 3 coils are faulty and I had 3 more with my 1st device.
Using low wattage could be possible, I frequently used my device at 35W despite my coil recommends 60-70W. Now I exclusevely use 65W but the liquid is still leaking through the coil.
The most possible problem could be the bad pg/vg ratio, however I live in Hungary and I can only buy one type of liquid. I need to mix the nicotine and flavour liquids "manually". Maybe my "mixing ratio" is the problem? I don't understand what actually pg/vg ratio is and how I can influence its effect.
Could you help me? I don't want to screw up my device again :'(.

To help hopefully clear things up a little for you @NapoleonHungary, it's not exactly a bad VG/PG ratio but quite possibly an incorrect one for the coils as it seems to be way too thin and is causing excess flooding that makes its way into the mod and causes the board to fail.

The solution is pretty easy, but will take a little trial and error to sort out. As what you'll be wanting to do is to increase the VG (Vegetable Glycerin) level of the liquid you use, as VG is thicker and therefore should reduce and or eliminate your problem.

PG (Propylene Glycol) is a very thin liquid and very easily wicked by coils, so if the ratio is too high you can see why the problem occurs.

Thank you very much for your quick response, I really appreciate it. I definitely try to pay attention and increase VG level however, in Hungary on e-liquids PG/VG ratio is not indicated but I guess I'll figure it out somehow

No worries at all @NapoleonHungary.

Ah, not declaring the VG/PG ratio makes things a little more difficult than it needs be.

One idea there may just be to look how easily it moves in the bottle, if it moves more like water skip it.

Then there's the other option, DIY.

Easy way there is to get your base VG/PG liquid, what are called one shots or flavour packs and then your Nicotine. It's a little more awkward than buying a bottle of liquid from a vape store, but it's the easiest end of DIY liquids and you can kind of get what you need then.

Oh, and you can with some choose what sweetener you want to use. As many have found Sucralose that's used in a lot of commercial liquids to gunk up and kill coils off.

Personally I'm a fan of using Ethyl Maltol for a sweetener, it's also sold as Cotton Candy flavour. That doesn't gunk coils up anywhere near the same so you get some good coil life using it.

Oh, totally forgot a hack for your liquid you'll like @NapoleonHungary.

You can thin high VG liquids with Distilled Water, use sparingly though as a little goes a long way.
