Hello guys, how can I boost the humidity up in my tent? I have a humidifier and the humidity is just sitting at 30? Ideas please? And also is it ok to mix liquid seaweed with other fertilisers? Specifically canna Nutes?

What humidity are you referring to, and how are you measuring it? If the humidifier is small and in your lung room rather than in your grow tent, that could be your problem. Also, if you are depending on the readout from your humidifier to measure RH, they are rarely accurate, and sometimes grossly inaccurate. For RH, get yourself some proper thermo-hygrometers, they are cheap and reliable, and can also help with your drying and processing. 
I'm pumping 3 gal a day into my grow room (72 sq ft) and my hygrometer has been sitting at 16 %
RH all January. Can't tell that it matters much.

It depends on your overall environment, growing can be done in low RH but medium moisture, cultivar, and temperature affect how much water is transpired/how well they do in low humidity. Going by VPD improves growth but to answer your question, depends on your overall environment.
Unless you don't exhaust, all that humidity you are trying to generate gets pushed out into whatever room the tent is sitting in. So humidity the entire room if possible to hit 50% RH, then your intake air is treated so no fucking with a stupid humidifier inside a tent(inconveniently dumb).
You can mix liquid seaweed into canna but is it from the Canna line? Are you using the full line?

Yes, I am using the full canna line, I’ve just heard that liquid seaweed is really good so wanted to mix a bit of that in there??
Seaweed contains nitrogen which is good for veg, but the canna lineup should have everything the plant needs without overcomplicating things.
I'd suggest keeping it as simple as possible with as little as possible - the less you use, the less there is to go wrong, and the easier it is to identify.

Along with the other ideas suggested above you can hang a wet towel with one end in a bucket of water and blow the air from you fan across it in the tent.
RH is one of the most important environmental factors in a high yield high quality grow. The stoma located on the plant leaves open and close based on the temperature and RH of the air around the leaf. If the stomata are closed transpiration is slowed or stopped. Transpiration moves the water bearing nutrients throughout the plant. If transpiration is not happening because the stoma are closed the plant cannot take up nutrients. This will lead to stunted growth and/or nutrient deficiencies. The ideal scenario is to follow VPD as close as possible. I live in a desert and it is nearly impossible for me to hit VPD most of the year. I shoot for and can remain >40% <65% RH most of the year. IMPO 30% is too low.
