Tomato leaves yellowing

  Possibly caused by lots and lots of rain.
  When the compost is saturated the roots can't take-up nutrients properly.
  Seaweed extract is great stuff but for tomatoes you really need to supplement it with a tomato feed.
  Tomorite is very good and has seaweed extract in it, but I'm going to try Chempak No4 as it will be quite a bit cheaper. I'll supplement with seaweed extract every couple of weeks too.

  A few of my bush type are doing the same, but I assumed it's because they were coming to the end of the road. This Romello for example has been producing tomatoes for 5 weeks now and only has a few handfuls left to ripen. Not sure if that's true or not? Do bush type plants continue to live on once all their tomatoes have been harvested...?

  I find they just go on producing flowers and fruit until the temperatures cool and the days darken - they just get slower and slower until they stop growing and start rotting.
  Those in my greenhouse are still trying to grow even though I stopped them a few weeks ago - some are even producing flower stems from the ends of leaves.

  I stop all mine by now. There's no chance of any flowers making viable fruit in time. That includes the ones inside. I doubt yours will do anything now @Glasgowgardener777, so you may as well remove a good bit of that foliage to allow the rest of the fruit to ripen. 
  I have a few outside, tucked against the growhouse, but they'll need to come into the house by the end of September, or possibly sooner, depending on how the fruits start to  ripen. Ones that were grown from a supermarket tom, and have done well. 
  The bush one I've been growing this year has been useless. Won't be bothering with it again. I had to re sow in early April, as the compost was terrible for everything I sowed in mid March, but still very slow, and even when I brought it inside, it's barely produced any ripe fruit. What it has produced tasted of nothing. Tumbling Tom - supposed to be pretty good, but not for me. 

  It's a place where beautiful isn't enough of a word....

  One of the ones that isn't doing well is Tumbling Tom. The other is in a large planter and is green but not much fruit yet.  All of them are not doing very well really. Quite disappointing.

  Can you helpful group please advise on why my outdoor pot grown tomatoes have yellowing leaves all the way up on the bush variety and only top3 or 4 green on cordon type. 
  Was it all the rain last month that caused it? I've been feeding weekly since the first flowers formed, with liquid seaweed. I know I might not save this year but be good to know for future. Plus if soil safe if compost. Thanks! (Thought I had a photo of the plant too, so I'll upload later)

  Weather without doubt....
