Cheers!Hi @TastyDerp and welcome to the planet.
Ive not seen or used this kit so having a quick google on it https://lostvape.com/product-item/ursa-quest-multi-kit/
coils and ratings are half way down the page.
the 0.6ohm coil is rated 20-28watt so best not go upto 35w as you mentioned as this will most prob burn it out.
0.3ohm is rated 30-40w. its best never to rely on ratings written on the coil so for me i would never hit 40w on these. im guessing 35w would be my max. if you wanted more cloud using higher watts then maybe the 0.2 or 0.15 would suit you better. for me though 3mg nicotine would suite these better.
i dont do nic salts but i believe these are best with mouth to lung coils at lower wattage. most salts are 50/50
now as you said the first tank tasted great and all you done was fill up and there was no flavour. could you of accidentally changed the setting to TC temperature control?
if you could post a screen shot of your screen it would help. apart from that i have no idea why the flavour would change dramatically just by filling the tank again.
oh and never appologise for writing too much. it makes our life a little easier to work out whats gone wrong.
So I'm almost certain because I've been chain smoking the vape, as I've had no flavour etc and kept trying to pull it through that it's clogged the cpil with gunk really fast and with the wattage not being high enough. With the 0.3 coil on a 30w setting the flavour is much better... I'll see how it goes, hopefully the coil won't clog up too much now with me vaping it less and on the correct settings. I'll send a picture of the vape later when I get the chance, thanks again!
