truss rod adjustments are simple
first thing you do is fret the neck at the first fret and the last fret and measure the distance between the string and the fretboard at like the 7th fret..if there is very little to o gap and the string is like brushing the fret ,then you have got a a back bow ..
if its a back bow ..turn the truss rod clockwise with an allen wrench.
the general idea is ..if you want relief ..loosen the rod (Counter clockwise) and if you want to tighten(which is your case)..turn the rod clockwise
just be careful ..and remember never to force anything ..beyond a certain point ,if the rod just does not budge ,take it to a guitar tech..
