If I have read your post correctly then you added 17.00 mil of flavor. This works out to around 13.75% of the whole volume of the total.
Not all flavoring are what we call shake and vape ejuice. Flavors need to age(steep) for a length of time before actually tasting like they are intended to taste.
If I can make a suggestion.....if you have a smaller bottle, put some of the already mixed ejuice in it and put the rest of original bottle away with the cap on and in a dark, cool spot. Then you can watch the progress of the smaller bottle as it changes. Shake it daily and taste it every couple of days.
The higher the volume of a bottle the longer stepping time takes.
If you want a true shake and vape ejuice then there are some I can suggest. Just know these would mostly be fruit mixes.
