Diy has no rights and wrongs, some people taste stuff at low as 0.05% and others might need a higher percentage. Theres nothing to feel bad about, but there is also a threshold.
Anyways just as I assumed yesterday, I’m kinda certain what the issue is here.
First I thought that you are one of the people that can’t taste strawberry what so ever. And while you might have a bit trouble with that, I’m sure its your equipment.
See here’s the issue I’m having, I hate saying that because I don’t want people to go out spending money. But maybe a bit down the road something to consider.
Your tank is a cloud chase setup, its extremely airy with high wattage coils and tons of cotton packed into it.
Its not for flavor and while you can pick up commercial juice while vaping on that, its complete different than our diy.
There’s a lot higher percent of flavors or/and higher concentrates been used, tons of sweetener, additives, pre steeped, some offer aged different ratios and this are just the basics lol.
Maybe give a flavor tank/setup a chance, you still can have a your huge clouds and wide open airflow
However you mentioned 10drop of custard in your coffee, that’s roughly around 2.3% . its not your taste buds man lol
But till there’s changes in equipment or not at all you’ll have to accommodate for it, and increasing percent till its high enough for you. But I’ve been there with same setup
So what I did was, I picked only heavier/darker fruits, thicker/darker/richer bakeries, creamiest and most overpowering flavors I could find and nixed these up. In the upper range of the threshold window tho.
I’d add mints or cooling to most of my juices, not the cap custard tho lol, only thing I somewhat could pick up with that setup and so on. So I suggest stick with earthier, bolder, Richer and darker flavors till time being. Not milder or delicate fruits like stoopid strawberry
The moment you change the setup, adjust the percent much lower and try to find your spot you enjoy etc. Hope it helped.
Edit: we could maybe add one more thing, if your flavors are older they might be done. Getting a new bottle somewhere and seeing if its different.
