Not sufficient downward force on the pressure foot.

Select the blind hem stitch. Be sure to have the correct presser foot. Then set the stitch width so the "zag" will catch the fabric fold and set the stitch length so there are probably about 10-12 stitches per inch.

here are some links for a manual

Good evening to you and your sewing machine.
If you have the manual there is probably a certain program for doing the hem this way in the machine.
If you are a little nervous of using the machine to do the hem you could do it by hand with what was called in my younger days " invisible stitch" or you can practice on a piece of cloth in the machine, take a look here Magic Invisible Closure and here

If you want it done entirely by machine you will need a special attachment. You'd have to check the make and model of your machine to find out if there is an attachment available from the maker. If not, there are some companies that make general attachments, and they'll list what machines these will fit. Check online sewing supply houses for this kind of thing.

You can also make one by hand. Any decent sewing book would tell you how. Usually you sew a straight stitch along the hem, using quite small stitches. Trim hem to a quarter inch from the stitch line. Crease the fabric or press it along the stitch line to the inside. Anchor your hand thread, then take a short stitch right along the stitch line. Next catch one thread of the fabric a quarter inch above the stitch line. It's just a basic running stitch, back and forth. Every few stitches, gently snug up the thread, which will roll the hem over. The finer the fabric, the smaller the stitches you take where they'll show should be.

There are some images that will help, if you enter the following search terms in google, you will see several pictures. Type the words," Illustrations for how to make a rolled hem by hand ? " and you will get a load of ideas.

it could be broken at the tip or dull, but it should be changed

Just trim the fabric to the desired hem length plus one inch, then overlock around this raw edge with thread close colour match to the fabric.

You then have the choice of either stitching around with a stretch stitch on your sewing machine, or hand sewing.

Being lycra shouldn't change how you hem them unless the trouser leg is extremely close fitting and the hem seam is going to be under tension.

My first choice would be using a twin needle in straight stitch from top side but this finish can pop/break if the hem is under tension. But perfect for most knit hems.

If you hand sew then you can turn up hem allowance and put a length of fusible hemming web inside the hem allowance and press it to hold. Then do a back stitch hand sew around to hold hem in place.

If you sew with the regular sewing machine, then use either the stretch stitch or a very small zig zag, and a ball point or stretch needle.

On ready to wear you would see a coverstitch hem but your overlocker doens't have this stitch.

blind hem foot is good if you want to machine stitch a hem but not have a seam showing. it will have an adjustable piece you can move left or right with a screw. but blind hemming works best on straight grain and not on a curve like a skirt hem unless its a knit fabric that gives. to make a blind hem press the hem allowance up then turn the main garment piece back to form a Z shape. you then stitch along the hem side with your blind hem foot guidr running along the top fold and use the blind hem stitch which looks like three little zigzags then one big zig far to the left onto your folded piece taking a little 'bite' - this stitch shows on the right side when you press the top of the Z back flat. so you need to adjust the foot position and how wide the needle swings to minimise this stitch showing. hope this makes sense and helps you with your sewing.

Your machine cannot do a cover stitch. Check the Brother website, they make a cover stitch only machine, it works much better than any of the serger/cover stitch combination machines, and it is a lot less money.
