Tiny leeks & onions

I sowed the seeds on 22nd March - Musselburgh leeks, Red Baron and Ailsa Craig onions. They took about three weeks to come through but, after a month of growing, they're still tiny - just little green strands.

Is this normal? I've never grown leeks or onions before. I'm just finding it really hard to believe they're ever going to reach edible proportions. All the books say you transplant leeks when they reach the thickness of a pencil, but mine aren't even the thickness of a pencil lead!

yep you have loads of time yet you can give them a feed if you wish but dont worry

My Musselburgh leeks are still puny and I sowed them a while ago. I potted them on today into a soil based compost but I put them in a big tub til they're big enough to be transplanted onto the plot.
