Welcome @GryphKat to our community 
That was a heck of an adventure for your first plant. But good practice for the new grow. Ilgm does have a real good selection and great customer service. But many of us do also try other places for seeds. What strains you thinking of trying? Again welcome!
I need something my pain clinic won’t flip over so I can use it all the time and these are listed as 20% CBD to 1% THC. They’re still adapting to cannabis usage being legal here (though selling still isn’t).
Good luck! We’re here for ya if ya need help or ya e questions.
Your humidity looks a bit low to me in the room for this stage. I don’t grow using this set up. Maybe wait to see what someone with more experience has to say. Happy growing to you though. 
Check out a couple strains to be some of the highest cbd growing cannabis known. One is ac/dc, the other is Charlotte’s web.
Looks like it could use water. You said the roots aren’t reaching water yet, so with this set up does the water drain straight to the bottom? Sorry, I grow in soil so not familiar with hydro
Correct! It very well could be a bit thirsty. My air stones are all in and on full, they create a lot of bubbles and that splashes the hydroton real well to promote the roots to keep going on down.
But I will give it some more cus why not
