Yellow leaves, deficiency?

[KellsSimon]

I have some young courgette plants and french beans in a bed and both are looking a little yellow floppy and lackluster.
It's the first time the bed has been used, as it was previously under slabs. I did add a dressing of chicken manure pellets at recomended dose.
Does anyone know what it might be? Defeciency of something or just to cold and exposed facing the irish sea?

If it has been cold and a bit wet with you that could explain the yellowing. Give them a bit of time and see if the new growth comes in greener.

Cheers Shirley,
It's not been too wet, but the nights have been a little cold.
Wierd thing is, is it only affecting one courgette out of four (so far) and only a couple of beans are yellow. New growth is coming through ok on the cougette though, but the whole plant feels floppy... i was just wondering if the soil could be the problem, or maybe some thing eating the roots? all a bit of a mystery to me but i hope it is just the cold, and things will get better...

If it's only a few plants - maybe it is due to root damage when the plants were transplanted (assuming they were)? I read something recently about "Faulty Root Action" (posh name for damaged roots?) which can account for plants failing to thrive after transplanting even if there are no obvious pests or other problems. I think one of my blueberry plants has got it!

My beans often seem to 'sulk' after being tranplanted. This year I have used seaweed extract as a foliar feed, and they're perking up well. I wouldn't worry too much, once the warmer weather sets in properly, you'll have loads of courgettes and will wonder what you were fretting about
