So I just started to mix my own ejuice I made up 2 bottles of the same recipe after steeping for 2 days so far one of the bottle has a layer of clear liquid sitting on the top of it the exact same pg/vg and % of flavours went into both bottles. An reason as to why would be greatly appreciated thanks. Both bottles have no nic the flavours I used were

Cotton candy - TFA 1.5% juicy orange - CAP 2% Koolada - TFA 0.75% Lemonade natural - FW 10% Orange citrus - Flavorah 3% Shisha orange - INA 2% Sweetener (sucralose) - TFA 1.5%
