I've managed to grow about 6 cauliflowers to this stage. It's the most successful I've ever been with brassicas so even if we just use the leaves I'll be happy!

All the plants look similar to this, the tips of the florets are turning purple. I can't remember if I planted a purple variety or not but is this normal? And the edges look to be browning and going weird - I folded over the leaves when they were growing as I was told that stops the sun ruining the florets.

Was this right? Have I left them in too long/picked too early?

Thanks in advance!!

Please help - I've got these little plants growing all over all my beds. What are they? Third picture is one that has been left to grow a bit more. And what's the best way to get rid of them all? Let them grow then pull up? How can I avoid this next time? I put 5cm of fresh compost on top of the soil before planting so not sure if these were contaminated in the compost or not. Thanks in advance!
