took the plunge last night and ordered mixing liquids and some flavours for the first time dont know where to start with mixing the flavourings though.
many people use a ejuice cacluator I did some research on different ones, and im going to use called Ejuice me up
eJuice Me Up - Best eJuice Calculator

found a how to use: eJuice Me Up
Interpreting the PG and VG % boxes and where to put what.
The first line is for the unflavored Nicotine eLiquid. It can be purchased with a number of PG/VG based percentages and strengths. Three boxes are provided for that info.
If you use Nicotine already at your desired strength and do not want to cut it, enter the strength in the Nic Strength box and 0 in the Target box.
If you are mixing Zero Nic and flavors only, enter 0 in both the Nic Strength and Target Nic box.
The second line has a box for what Nicotine strength you would like your final result to be after adding all of your ingredients.
The third line (Amount to Make) is self explanatory.
The forth line (Water/Vodka/PGA) is also self explanatory. I rarely use this. PGA is Pure Grain Alcohol
The fifth through the ninth line is for the flavoring you are adding. I rarely use more than 20% flavoring, mostly 12 to 20% and that depends on the potency of the flavoring. If you're using more than 1 flavor, they should all add up to the percentage I mentioned. NOT 20% each but say 10% + 10% for two flavors.
NOTE: PG% and the VG%: most flavoring is PG based. In that case you would put 100% in the PG box. What you put in the PG or VG box is deducted from the amount of PG/VG you add which cuts the Nic down to the Target Strength.
There are only a couple of companies who do not use PG or VG so you can check the Flavor Zero PG/VG box on the Flavoring row.
Further down there is the "Resulting Recipe".
The PG% and VG% boxes are to change the final eJuice PG/VG out come. In other words, what you want your eJuice to be.
If you receive a warning pop up to add VG or PG that is because the calculator came up with a negative number. Adjustments will have to be made. Say you have a negative for PG, you will then make the PG% higher until it shows 0.
Up on the Menu, "File", "Save As Default", you can now Save your settings as a default which will load your settings when the program first opens. You can create several default files by naming them what ever you like. Note: on start up, the Default.dft file will be called first.
The button at the bottom which use to be "Rest" is now called "Get Default" will open a Dialog box to select a Default file that you saved.
the rest you can find out more, when you download it, select website link at top and choose How to( this is where i copied and paste most of the how to, but there is more to How to..
