They are no good to use as the centre is like a piece of wood. How do I stop this?
Warm weather will cause the Leeks to bolt,this is out of your control.
Don't fertilize as this will cause them to grow faster.

I have some leeks planted. Some of them now have what looks like grass heads. Are they going to seed? Thank you!
Thank you @Downtoearthdigs! It appears the whole pack is grass seeds then ...!
This appears to be a grass, it is not Leeks.
The seeds may have blown in or even carried by birds.
These articles have images and more information on Leeks.

I live in temperate zone (Gippsland Vic.) I planted my Leek seedlings last October. I've followed all the instructions on the tag that was on the punnet. It's now Feb. and my Leeks still look like they're spring onions. I don't understand what's going on; please help me. Thank you, kind regards.

I have the heads with seeds in them. Can I dry these heads for seeds to start my crop of Leeks next spring. How do I dry the seeds and store them until spring?
I recommend drying the seeds on your counter on top of a paper towel. This method is tried and true with me. After they dry for a few days, then put them in a bag, or glass jar and save them in a cool dark place, such as a box, in your closet, or a drawer.
Is it ok to overwinter these two items, living in Colorado at 5k feet Sone 5 I believe. If not I will have to harvest TODAY:) Thank You Kindly, J. Milano
Leeks can survive frost and can retain quality even if temperatures drop as low as 20 F. Below this they may lose quality. Onions are similar, see this article for more:

All all purpose vegetable fertilizer can be fine, but I would recommend, instead, to till in some compost into the top layer of soil. This will take care of the nutrient content and prepare to plant with something else.

found a couple of little worms on them.
There are many insects that will attack them, but this can be a sign of overwatering rot, as well. This can lead to maggot infestations.
What I can do, for now, is point you to some articles that will help you, here:
