This may have been answered already, but is anyone else having wicking issues with the thick single thread version of the wicks that came with many of the 2.8 ohm heads? I have major issues with dry hits on those heads, but no problems on the 1.8 and 2.4 ohm heads with the 4 slender wicks.

I'm having some issues with the dry hits; seems a new head works great for a couple of days and then the wick doesn't seem to absorb enough liquid. Switch heads and it's fine again for a couple of days. It's happened to me with all 3 heads so far. Tomorrow I'll reinstall one of the previously used heads and see what happens. I use only very light liquid--almost no color at all so it's not the juice

I'd still suggest you clean and dry burn them first... just to be certain

What does your coil look like ? Is it all gunked up looking ?

Not on the 2.8 heads... it's my favorite one. I can go all the way to dry tank before it dry hits. When it's low on juice, I do roll it to make sure it's getting in the juice. I'm also careful to wash it every two days too.

Ive been using my nova v2 for about a week and a half now. So far I really like it but I've been having trouble with the 1.8ohm heads. I can't get through one tank without the burned taste and the coils turning black. I like the performance of the 1.8 over the 2.4 but I'm going through one a day. I am using a 50/50 mix at 24mg fairly clear juice. I'm not sure what else to do. Maybe I should try the V2.5 heads.
Any advice would be appreciated because I would really like to keep using the Nova I just don't want to replace the head after every tank. Oh and I forgot to say I'm using it on a standard 1100mah Kgo battery.

That is so strange. I have the exact opposite problem, regardless of PG/VG blend. Do your 2.8 heads have the single thick braided wick? Are they long wicks? Do you trim them?

I could not wait for GV to get more 2.5 in stock so I got one from another vendor. There is a much bigger difference on the 2.5 than 2.0. This one actually works. The 2.4 head + 7 watts on kick on my SB 18500 is great. The flavor was slightly muted at first but after leaving the tank filled over night, it was good. If I chain vape, I get a dry hit here or there but a nice primer puff fixes that. I actually now know why people are enjoying this.

Yes, a single, long, thick wick. I did try trimming one on the V1, but I think it was a 2.4Ω. I’m using a 2.8Ω (after a clean and dry burn) and unraveled the wick – does seem to over wick on occasion, but not excessively. Straight VG can sometimes be a problem – if your juice is very thick try thinning a little with a little bit of PGA (or vodka), or water. Dry hits are most often a wicking problem.

I have noticed that there is a difference when using different APVs. I use a switching regulator VV most of the time and it’s set pretty close to the lowest setting to get a nice cool vape. I got a commercially produced PWM device and at 3V it’s still way too hot – I just don’t think it’s calibrated properly. On the iTaste VV it does pretty well.

Not at all; after just a couple of days it looks fine; I also notice that once the juice gets to a certain level---about 1/2 full, that's when I notice the dry hits; a few times upside down and everything is fine for a little while.

That's how I use mine, tilt it up to keep wicks submerged while vaping and kinda rotate it at same time never any dry hits.

The heads are interchangeable. The depth of the metal is not the same and the rubber tips need to be changed to the type of unit your installing it in. Once your install the rubber tip for the Stardust on the vivi head, it will fit just fine. I am using vivi heads in the new stardusts.

Do the heads on the replaceable stardust work on the Vivi Nova? What are the differences in the mini Nova and the Vision 2?

If you havent already, unravel the wick. Should fix the problem. If not its either the juice is too thick and adding a drop or two of distilled water will fix that, or the voltage is set to high.

The only things I can think of at the moment without knowing what pv you use and your settings.

Tried all of the above. Thanks for the input, though. I'm just going to stick with the 2.4s for now. Maybe trimming the wicks will help...

No need to change the rubber out. The Vivi head will seal up nicely on the Stardust, with it's original tip. I like them better than the Stardust heads, so all of mine are now using Vivi heads. :)
