I have some potted tomato plants and the soil just started turning yellow on top. It is spreading over the whole top of the pot.
You have some type of slime mold forming on your soil. While this will not affect plant growth, other than shading out light, you may want to consider repotting with fresh soil. Here is more information: http://msucares.com/pubs/infosheets/is1684.pdf
I have planted over a dozen tomato plants in containers as I do every year. I amended the soil with manure and dolomite and some organic fertilizer. I noticed in the past week the leaves are fading from a dark green to pale green without too much growth. What could be causing this? We have been having some crazy weather here. Very warm and very cool. Thank you.
It may be chlorosis. This article may help:

Two weeks later and tomato plants are robust! I did nothing but wait and it surely paid off.
Last year I grew tomoatoes on my balcony. I pruned all the suckers. The darn things grew up to the top of the balcony, hit the ceiling and then kept growing (bending over). Should I trim the top of the plant so that it does not get too tall? There was no way I could reach tomatoes that high! With only one stem, they did not get very bushy.
I would not prune the suckers out this year. Removing the suckers encourages the plant to grow up instead of out.
I have a tomato plant in a container and the top leaves are turning yellow/white. Can I save this plant?
Is it recently planted? It sounds like it may have sunscald, which happens when plants are not properly acclimated. If this is the case, the plant will recover. The burned leaves will die while new ones will grow. It will just take a little time. This article will help with acclimating in the future:

At the bottom leaves on my tomatoes, they have turned yellow. i am growing them in my greenhouse in tubs of compost and some of the leaves near the top on some of them are curling up. What should I do?
It sounds like they may have a blight. These articles will explain more:

Just read the article on fertilizing tomatoes. I use the Epsoma Tomato fertilizer and gave some to all the tomatoes when I planted them. The ones we planted in containers are setting fruit, but I am wondering if I should give them a bit more of the fertilizer now or wait a while since they are in containers? What do you think?
For container tomatoes, I would use a slow release fertilizer. Since they can't spread their roots out and continuous watering washes out fertilizer much faster, a slow release fertilizer makes sure they get ongoing nutrients. Slow release fertilizer is also good to keep the roots from burning from the fertilizer in the container.
