Assuming you took care of the vacant spaces @gsmit1 pointed out earlier, I think you might not be using enough cotton. On your next wick, try a slightly wider piece of cotton (like 0.5mm wider) in each coil and longer tails to make sure you are filling in your juice wells but not tight (not super loose either).
It's hard to diagnose what's wrong, but you have to keep trying and don't do more than one or 2 new things at one time so you can pin point what fixes your problem.
