Hi tiffa, welcome to FC. I'm sorry if you went and got this tank based on reading my posts and expected it to not leak on you based mostly on that. I may not have mentioned it specifically, but using the RBA coil is essential to this tank / atomizer combo not leaking out on me. I've had em sitting around for months now, refilled several times, standing up straight, laying sideways, upside down, every possible angle, hot cars / pockets, no leaking. The donuts in my coil get "flooded" but that is by design, and I'd rather consider my coils "saturated" or "soaking" which helps yield the smooth, rich, repeatable, tasty clouds they deliver. Avoiding spitting with thick distillate and co2 oils on a "saturated" RBA coil is easily controlled by the air throttle, too.
I may not have pointed it out, but the default coils for the smok X-baby tank with top-airflow (and all of their standard, bottom-air tanks) have the possibility to leak / flood out. You might even say they are prone to it, or that it would be inevitable.
I took some pics to illustrate how this could be
The RBA coil is on the left, standard on the right
the top of the coils pictured above
and the bottom
The X-baby is the only tank from smok with top airflow, which is necessary for any tank design to truly be leak-proof / leak resistant, IME. But simply having airflow enter from the top is not enough. Some top-air coil designs still route the airflow through the bottom of the coil and provide a hole at the bottom of the coil where oil / juice could possibly seep out, into the metal base of the tank, which could easily hold 1ml of juice, a gram of oil, or more! The vaporesso veco has a similar air flow dynamic going on, and fortunately I've heard of only 1 or 2 people having that problem with the veco coils flooding, but no leaks for everyone else it seems (the veco didn't leak on me also)
For the x-baby tank, you need to use the RBA coil, with it's fully sealed-off bottom floor, to be 100% leak free. All the air is routed internal to this coil, so there's simply no place for it to leak out from, if you have everything twisted in tightly.
That's the other issue that may be causing problems here.
Many times, with nicotine juice applications, which this stuff is actually intended for, people don't see leaks that much. With the lighter viscosity / weight of the e-juice, the cotton can act as effective barrier and prevent the coil from getting flooded and leaking out. Other times, it does leak out.
Hard to tell exactly why it does and doesn't sometimes.
But with your questionable terpene supply, it seems you are blowing out seals and dissolving them through, which makes it very tough to expect most tanks to not leak on you. With a tank like the cubis pro mini and the RBA coil for the x-baby (these are true top-air, non-leak tanks) you can still manage to keep your highly solvent mix from leaking out. The terpenes might eat up a silicon 510 plug and ruin the coil, but it won't leak out at least.
Even the humble little liberty V9 carts offer a truly sealed bottom cup & center post design that really don't leak, they can TC, are easy to fill and they vape ok, and are newb friendly
But i would also advise a step-back for context....why tank? why terpenes? why pg and vg also?
I see you're a fan of vaping on tanks, that's cool, and you want to do CBD, but are you adding terpenes just to liquefy the CBD crystals for the tank, or for added medical effect, or some combo of the 2?
Like inverted had advised you, If you just want to vape CBD and aren't too keen on the terepenes, and you're ok with the occasional reload, I would try out some load-as-you-go atomizers actually intended for vaping concentrates. Ceramic donut types are the better type IMO, but you can get metal coil types as well. Then you can use less / no terpenes and not worry about anything leaking or getting dissolved.
