i am sub ohm vaping @31.5w isub and 40w protank 4 , so i should put 2.5ml flavoring ??
How many
mL of flavoring you'll use in each bottle of eliquid you make...is dependent upon 2 things: (1) how many total mL of eliquid you're making, and (2) what % of each flavoring you're using to make that amount of eliquid. It won't be a set amount of mL across the board for all recipes, nor every eliquid amount, that you're making.
What I mentioned above in 1 of my posts, was a recommended
% of flavoring, not mL, for the
One Stop Flavors and One Stop Blends only (ie. the Tobacco Blend, the Tennessee Whiskey, and the Wild Cherrylicious). Manufacturers of the single flavorings you bought (TFA, CAP, and FA) do have recommended % to use
their individual flavorings at in an eliquid recipe, too. They can be found on their own websites, and I think even in a forum or 2 maybe on the ECF.
So, for
only the One Stop Flavors and One Stop Blends above...the owner recommended that if you're
subohming, use about
5% of just 1 of them in with your PG, VG, and Nic Base. If you're making a 50mL bottle of eliquid...that 5% is 2.5mL. But if you're making a 30mL bottle...that 5% is only 1.5mL of flavoring. All recommendations anyone gives are only suggestions, too. Your
own tastes will tell you whether more or less suits you.
Also, for your first 4 flavorings that you ordered, I can't offer any advice about what % to use for each of them. Those are
single flavoring, that most people use in combination with other single flavorings to make a recipe. As far as I know, the vast majority of those who DIY don't vape just single flavorings + PG, VG, and Nic Base...unless they're like the One Stop Flavors and Blends (which are several flavorings already combined into 1 bottle for you). Those are the
only ones I personally use singly, of the 124 flavorings I have.
I also agree with ronnbert above about making very small 5mL or less sample amounts...to taste test and vape test a few drops at a time, as you make any changes to get them exactly as you want them within that small amount. Make sure you take notes about any changes you made in the test sample, too. You'll need those notes when you input info. into an eliquid calculator to have it determine how much of each ingredient you'll need to make a larger bottle of it, so it turns out the same!
About buying syringes, blunt needle tips, etc. If you have a Tractor Supply anywhere near you, or a feed store (sells livestock supplies, feed, meds, etc.)...you can get syringes there for
very cheap prices and in many sizes (3mL through 60mL)! Blunt needle tips in 14ga and 16ga are IMO the most useful sizes, and can handle the PG, VG, and flavorings very well. I'd get at least 4 of each of those gauges (they're cheap online @ about 35c - 50c each).
