Having done a bit of research, I'm pretty sure that that tomato plant has a severe potassium deficiency - http://www.hbci.com/~wenonah/min-def/tomatoes.htm has a good set of pics of toms with various types of deficiency. Comfrey tea would definitely help if you could see your way to bunging a bit on, it's high in potash, as would wood ashes. Other than that, it may simply be a matter of the plant getting fully established.
It's a bit odd that potassium levels are so low, if I've got this right, given that the beds are completely full of organic matter. I think I'll take a sample of the compost next time I'm there and do a K test on it. Should have thought to take a sample this time - actually, can you give Matt some to bring over on Saturday if you're not coming yourself.

That tea in the polytunnel lookes pretty well rotted and smells foul so I think it's nearly ready. I'll put it on soon.
ReplyDeleteI'll also add some wood ash.
