Does anyone here know how to condition your pinky for hammer ons and pull offs? Cause all my other fingers are good, but I can't seem to get this one to go with. Thanks!
Just practice pull-offs/hammerons with each finger, on every string.

1h4p1 'till you got that down, then
2h4p2, then 3h4p3

Do that on every string, as a part of your usual routine.

And yeah, pinky hammer-ons suck.
Pinky hammer-ons are absolutely marvellous. Some of the best guitarists in the world don't use their pinky at all, so get used to it because you'd then have the potential to play 1/4 faster and have an easier time when stretching to notes. Personally my pinky, when my index is on the first fret, can reach to the seventh.
