Im using awt 18650 3000mah 40A battery, 65vg 35 pg no.nicotine.cheese cake.
First of all, I have no idea why you are associating the type of mod you're using with what the coil builds within your atomizer are doing.
Second of all, that battery is not 40A, not really pointing this out for you, more for new vapers who may read this. The battery DOES have a 40A rating for a pulse discharge, but it's a re-wrapped 20A continuous rated LG B-Bin cell in all reality. There isn't a single 18650 currently in existence that can truly advertise a maximum discharge rating above 30A continuous. The problem is, especially on re-wrapped cells, they typically print the higher pulse discharge ratings on the wraps to give less educated customers the illusion that the cell is rated much higher than it actually is.
Third, if cotton is present inside your coils you definitely under no circumstances should be witnessing glowing red spots anywhere on the coils.
Four, when you put your coils in the RDA, make sure all the connections are screwed down well, then try to level out the coils equally with a screwdriver or whatever you wrapped the coil with. Then, without cotton in them, get them glowing red and pinch them until the coils have compressed and are touching. Then, with a small flat head, paperclip, or any thin object, begin heating up the coils. If you see hot spots (parts of the coil where the resistance is not on a mean level with the other parts, causing it to draw more power and burn hotter, thus brighter) which usually appear in streaks, begin raking the metal across the areas where the streaks were shortly after (but definitely not during if you're using a conductive material) heating the coil up to witness them. When all is said and done, the ideal situation is both coils sitting evenly in their respective positions, and they heat evenly when fired and also glow evenly.
Five, when you do put cotton in the coils, make sure they've cooled down if recently heated. Then, the amount of cotton you want to put in the coils will be roughly the same as the inner diameter of the coil itself. When you insert the cotton, you want it to appear to fill all of the inner coil, but also have a LITTLE bit (not a lot) of give when you pull at the ends. Then take out your juice, saturate well and off you go into fun land.
IF your coils ARE burning red while cotton and (especially) juice are present within them, you have either built very poor coils (or have secured them poorly within the post connections) that are shorting / hot spotting all to hell OR alternatively, aren't using nearly enough cotton / juice.
The fact that they are burning red means the coils are literally BURNING the cotton. This will definitely mess up the flavor, for obvious reasons. When you have a properly built, wicked and juiced coil build in an atomizer and begin applying wattage to it, you should see vapor rapidly rising off of the coils, droplets boiling / vaporizing off of the coil wraps and also hear a hissing sound. If it doesn't look and sound like this (besides the occasional popping which is normal) you have a definite issue that needs to be addressed.
